Based on this concept, the green plants are called primary producers and the heterotrophic organisms as the secondary producers. For example in the deep oceans producers are absent. Answer: The structural component of an ecosystem may be classified under two main types: 1. You can change your ad preferences anytime. Name the types of nitrogenous bases present in the RNA. The abiotic component of ecosystem consists of kinds, quantity and distribution of physical and chemical factors such as light, temperature, water, oxygen, carbon, nitrogen, and minerals. The components of the Grassland Ecosystem are discussed below: 1. Decomposers or the micro-consumers are also called the saprobes or saprophytes. Producers are largely photosynthetic plants and their kind varies with the kind of ecosystem For example, in a dense forest the trees are the most important producers. The structural components of roof decking in case of pitched roof is generally a truss, in case of curved roof it is a shell or dome and in case of flat roof it is a flat slab. When an ecosystem is nourishing (or sustainable) it means that all the components are present in balance and are able to reproduce. 1. Green plants are the predominant producers; animals, the consumers; and fungi and bacteria, the decomposers. are some examples of natural ecosystems whereas aquarium, park, crop-field etc. v The various biotic components, representatives from the three functional groups, of a forest ecosystem are: 1) Producer Organisms v In a forest, the producers are mainly trees. These include plants, animals and micro-organisms (bacteria and fungi). What are the characters Mendel selected for his experiments on pea plant? (b) Heterotrophic component {heterotrophic = other nourishing, which utilizes, rearranges and decomposes the complex materials synthesized by the autotrophs. The structure of an ecosystem describes its environment and physical features. If the balance is disturbed, the whole system breaks down. An ecosystem is a term first used by a Tansley, an ecologist from Britain, to mean all of the organisms in a particular environment and how they interact. Every ecosystem has two components, namely, biotic components and abiotic components. 2. A constant input of solar energy is the basic requirement for any ecosystem to function and sustain. The energy is in the form of light, heat, and stored energy in chemical bonds. As mentioned above, for the proper functioning of an ecosystem, there must be a continuous flow of energy and cycling of minerals among the organisms of the ecosystem. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. ecosystem The following chart shows the types of Natural Ecosystem − Abiotic Components The various structural components of an ecosystem are classified under two main groups, viz., (i) Abiotic or Non-living; and (ii) Biotic or living. However, some ecosystems may lack one or another of the components. Biotic Components (Living Components) The biotic or living components of the ecosystem comprise the kinds, numbers and distribution of living organism. They derive their food directly or indirectly from the producers or the green plants. Each ecosystem has characteristic physical structure resulting from the interaction of abiotic and biotic components. The various structural components of an ecosystem are classified under two main groups. From the structural point of view, each eco-system has two basic components: 1. An ecosystem is a group or community composed of living and non-living things and their interactions with each other. For example, a deer or a giraffe is a primary consumer in a forest ecosystem, while a cow or a goat is a primary consumer in a grassland or crop ecosystem. Biotic component of the ecosystem includes the living organisms; plants, animals and microbes whereas the abiotic component includes inorganic matter and energy. The four components collectively function as a whole system to maintain the stability of an ecosystem. Share Your PDF File Next, we show how those distinctions add to our appreciation of another conceptual model that depicts degradation as a stepwise positive feedback cycle. Privacy Policy3. An ecosystem is also defined as a functional and structural unit of Ecology. 3) Climatic regimes – Temperature, Mois-ture, Light & Topography. Share Your PPT File. 2 Our mission is to provide an online platform to help students to share notes in Biology. In this type of classification, there are: Autotrophs and Heterotrophs Organisms that produce their own food from an energy source, such as the sun, and inorganic compounds. They also include some organic matter, such as the amino acids and other products of decay of living things. But their place is taken by the rain of dead decaying protoplasm that sinks from the surface. Welcome to BiologyDiscussion! While the materials circulate, the solar energy is continuously trapped by the green plants on the one hand, and lost in space through respiration and loss of heat by all types of organisms, on the ether. In a pond, the aquatic bacteria, flagellates and fungi are distributed throughout, but they are especially abundant in the bottom, where dead bodies of plants and animals accumulate. Yeast: Origin, Reproduction, Life Cycle and Growth Requirements | Industrial Microbiology, How is Bread Made Step by Step? This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. The secondary consumers (carnivores), such as the predaceous insects and game fish in a pond, feed on the primary consumers. In lakes and ponds, the producers are rooted or large floating plants and microscopic plants (phytoplankton), usually the algae. The components of the ecosystem are divided into abiotic and biotic. The ecosystem is largely divided into two functional components; the Abiotic and Biotic. The primary consumers in an ecosystem are herbivores, which feed directly on the producers (green plants). Another important type of consumers is the bottom-living detritivores, which subsist on the rain of organic detritus from autotrophic layers above. Structure . However, primary consumers also vary with the kind of the ecosystem. The Biotic components are further categorized into three based on their functions in the ecosystem as producers, consumers, and reducers or decomposers. Molds and mushrooms (Agaricus) of the forest floor are the largest of the decomposers that are visible to a naked eye. The components ofan ecosystem 4. See our Privacy Policy and User Agreement for details. The abiotic components form the physical environment of an ecosystem include factors such as energy, elements, inorganic compounds, dead organic matter and climate. 1. The role of decomposers is very important in an ecosystem, for without their activity the entire cycle of minerals will get blocked. 2. 1. The zone where two or more different communities meet and integrate is … We observe that organisms living in any ecosystem are nowhere identical, but can be categorized into species. Content Guidelines 2. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. But an ecosystem is not truly complete without considering the non-biological, or abiotic, components … However, some ecosystems may lack one or another of the components. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. We will consider an ecosystem from a structural perspective. The functional attributes of the ecosystem keep the components running together. Organisms that consume other organisms as a food source. The consumer animals ingest plant products or other organic materials as food, break them in their digestion process and produce the new types of organic materials like the proteins and animals tissues. This includes the distribution of energy in the environment. An ecosystem has a physical environment, or factors, biological components and interactions between them. 2) Organic compounds – Protein, Carbo-hydrates, Lipids – link abiotic to biotic aspects. Structure and Function of an Ecosystem: Each ecosystem has two main components: (1) Abiotic (2) Biotic (1) Abiotic Components: (With Methods)| Industrial Microbiology, How is Cheese Made Step by Step: Principles, Production and Process, Enzyme Production and Purification: Extraction & Separation Methods | Industrial Microbiology, Fermentation of Olives: Process, Control, Problems, Abnormalities and Developments, The best answers are voted up and rise to the top. Clipping is a handy way to collect important slides you want to go back to later. Or simply, we can say ecosystem functions relate to the structural components of an ecosystem (e.g. An ecosystem consists of two components: A. Abiotic components: They are the non-living components of the ecosystem which include; Physical environment: It includes basic in-organic (soil, water, oxygen, calcium carbonates, phosphates etc.) The materials are like water, minerals atmospheric gases, and salts. These are called the tertiary consumers. Therefore, animals are also busy in the process of organic production. Source: www.csun.edu/science/scale/4th_grade/ppt/energy_ecosystem.ppt, 1. Species composition and stratification are the two main structural features of an ecosystem. The food is then digested, i.e., broken down to simple substances which are metabolized in the consumer’s body and the waste products of their metabolism are released to the environment. The inorganic elements and compounds found in the ecosystem consist of all nutrients such as nitrates, phosphates and sulphates, water, carbon dioxide and oxygen etc. Biotic component. Presentation on : Structural component of An ecosystem is a self-contained unit of living things and their non-living environment. Most regions—with the exception of rock outcrops, dry ridge tops, and river gravel bars—are fully vegetated, primarily by dwarf shrubs, lichens, and mosses.An ecosystem can be categorized into its abiotic constituents, including minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consisting of all its living members.The fundamental source of energy in almost … structural complexity on different components of the eco-system and ecosystem services. Other aquatic communities are sometimes devoid of consumers for short periods, and decomposers will attack the producers directly, although usually only when the plants are dead. Microscopic animals, such as the protozoans and certain crustaceans, which feed on the floating algae of ponds and seas, are the primary consumers in their habitats. v Trees are of different kinds depending upon the type of forest developed in that climate. The Components Of Ecosystems4• The structural components of an ecosystem consist of nonliving arena and theliving organisms.• Examples of the abiotic component comprise the soil, atmosphere, solar radiation and water. Before sharing your knowledge on this site, please read the following pages: 1. The most intense heterotrophic activity takes place where the organic matter accumulates in the soils and sediments. This implies that each ecosystem has a definite structure and components, and that each component part of the system has a definite role to play in the functioning of the ecosystem. By : Dhruv M Patel(16BEECV084) The whole process is called mineral circulation or the bio-geochemical cycle. Yet the same basic ecological components are present (with the few exceptions discussed below) and function in more or less the same manner in all types of ecosystems. Examples of ecosystems are forests, lakes, or deserts. Let’s discuss them in detail. TOS4. 4) Producers – Plants. Any ecosystem is characterized by a set of abiotic and biotic factors, and functions. However, whether large or small, rooted in the soil or floating in the water, all producers support an array of consumers and decomposers. If you continue browsing the site, you agree to the use of cookies on this website. The structural components of the ecosystem are producers, consumers, decomposers, gases, water, etc. 1. (160410111045). Q.1 Describe different components of ecosystem in brief.4. A small portion of these nutrient materials circulates through other living components of the ecosystem and through their death and decay returning to the soil and the environment. They can be natural as well as artificial. Decomposers are sometimes also called detritivores, particularly when they break down animal and plant material called detritus. An ecosystem can be as big as an entire ocean or as small as a drop of water. nections between structural and functional components of rangeland ecosystems and also on distinctions and con-nections between biotic and abiotic components of the ecosystem. They are also the living components, chiefly the bacteria and fungi, that break down the complex compounds of dead protoplasm of producers and consumers, absorb some of the decomposition products, and release simple substances usable by the producers. Which organelle is known as “power house” of the cell? Abiotic components . plants, water, soil, air and other living organisms) and how they No public clipboards found for this slide. ECOSYSTEM Structural aspects Components that make up the structural as-pects of an ecosystem include: 1) Inorganic aspects – C, N, CO 2, H 2 O. Abiotic Components: These are non-living thing components consist of carbon, hydrogen, sulphur, nitrogen and phosphorous etc. Stability and Structure of Ecosystem (With Diagrams), Ecosystem Functioning: Self Regulating, Self Sustaining. Consumers are those living organisms that ingest other organisms and are, therefore, called heterotrophs. These species present provide their contribution towards an ecosystem. The biotic components of an ecosystem can be classified according to their mode of energy acquisition. Abiotic. These functional components of an ecosystem are arranged in overlapping layers with the greatest autotrophic metabolism occurring in the upper stratum where light energy is available. It also includes the climatic conditions prevailing in the environment.The structure of the ecosystem can be split into two main components namely: 1. Components of Ecosystem. For example in the deep oceans producers are absent. Thus, in an ecosystem, the first three of the four structural components are composed of living things. Components of Ecosystem. Grassland, pond, desert, forest, sea etc. Biotic Components 2. An ecosystem is a discrete structural, functional and life sustaining environmental system. Ecosystem functions are the physical, biological and geochemical processes that take place or occur within an ecosystem. The abiotic component consists of two things: the materials and the energy. The vast majority of consumers are the animals. The roof covering or roofing which is provided over pitched roof could be in the form of tiles, slates, A.C. sheets, G.I. The ecosystem of distinct terrestrial areas with climax plants and associated animals are known as biomass. Share Your Word File In the ocean, the rooted and floating algae are the producers. The abiotic component of the ecosystem refers to the physical environment or the non-living factors. The energy flows through an ecosystem on a one-way traffic and for the proper maintenance of any ecosystem the energy must be consistently added and transferred from organism to organism. are artificial ecosystems. The function of ecosystem is related to the energy flow, decomposition, nutrient cycling and major biomes. Components of an Ecosystem. Answer Now and help others. If you continue browsing the site, you agree to the use of cookies on this website. Finally, Abiotic component. Components of Eco-System: The structure of an eco-system describes the composition of biological community, physical features of environment including the quantity and distribution of nutrients in a particular habitat and climatic conditions prevailing in the area. Every ecosystem has the following four structural components: Producers or the autotrophic organisms are those living members of the ecosystem that utilize sunlight as their energy-source and simple inorganic materials like water, carbon dioxide and salts to produce their own food. According to Odum, from the trophic (food) point of view, an ecosystem has two components: (a) Autotrophic component (autotrophic = self nourishing), in which the fixation of light energy, the use of simple inorganic substances, and the manufacture of complex materials predominates. Disclaimer Copyright, Share Your Knowledge There are, in most ecosystems, some organisms that eat other carnivores like snake eats a frog, or a bird eats all types of fishes including carnivores. and organic compounds. Why mitochondria is called as the power house of the cell? Ecosystem functions are natural processes or exchange of energy that take place in various plant and animal communities of different biomes of the world. Some ecosystems may have the top carnivores like the lion and vulture, which are not killed or rarely killed and eaten by other animals. See our User Agreement and Privacy Policy.

An ecosystem consists of biotic and abiotic components. It is quite obvious that the different ecosystems are populated by entirely different kinds of organisms, with the possible exceptions of a few kinds of bacteria that may be able to live permanently in many or possibly all ecosystems. Green plants are the predominant producers; animals, the consumers; and fungi and bacteria, the decomposers. A much larger portion of the materials is held in reserve in the environment as well as in the organisms themselves.
