4) Producers – Plants. But their place is taken by the rain of dead decaying protoplasm that sinks from the surface. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. An ecosystem consists of two components: A. Abiotic components: They are the non-living components of the ecosystem which include; Physical environment: Structure . Abiotic components Biotic components comprise the living organisms present in an ecosystem. 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. The secondary consumers (carnivores), such as the predaceous insects and game fish in a pond, feed on the primary consumers. Before sharing your knowledge on this site, please read the following pages: 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. Thus, in an ecosystem, the first three of the four structural components are composed of living things. From the structural point of view, each eco-system has two basic components: 1. 2. 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. Every ecosystem has two components, namely, biotic components and abiotic components. However, some ecosystems may lack one or another of the components. Content Guidelines 2. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. Presentation on : Structural component of The zone where two or more different communities meet and integrate is … Ecosystem functions are the physical, biological and geochemical processes that take place or occur within an ecosystem. 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. The Biotic components are further categorized into three based on their functions in the ecosystem as producers, consumers, and reducers or decomposers. If the balance is disturbed, the whole system breaks down. Variables describing hydrological structure, biological structure, element storage and cycling, and organic matter accumulation were classified as structural components or biogeochemical processes according to wetland functions described by Smith et al. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. The role of decomposers is very important in an ecosystem, for without their activity the entire cycle of minerals will get blocked.

The four components collectively function as a whole system to maintain the stability of an ecosystem. Examples of the abiotic component comprise the soil, atmosphere, solar radiation and water. A constant input of solar energy is the basic requirement for any ecosystem to function and sustain. The biotic components of an ecosystem can be classified according to their mode of energy acquisition. An ecosystem consists of biotic and abiotic components. Welcome to BiologyDiscussion! These species present provide their contribution towards an ecosystem. 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. Answer: The structural component of an ecosystem may be classified under two main types: 1. For example in the deep oceans producers are absent. Finally, The energy is in the form of light, heat, and stored energy in chemical bonds. The whole process is called mineral circulation or the bio-geochemical cycle. Any ecosystem is characterized by a set of abiotic and biotic factors, and functions. An ecosystem is a self-contained unit of living things and their non-living environment. The roof covering or roofing which is provided over pitched roof could be in the form of tiles, slates, A.C. sheets, G.I. See our Privacy Policy and User Agreement for details. Decomposers are sometimes also called detritivores, particularly when they break down animal and plant material called detritus. Organisms that consume other organisms as a food source. For example in the deep oceans producers are absent. The following chart shows the types of Natural Ecosystem − Species composition and stratification are the two main structural features of an ecosystem. An ecosystem is a discrete structural, functional and life sustaining environmental system. The abiotic component consists of two things: the materials and the energy. Green plants are the predominant producers; animals, the consumers; and fungi and bacteria, the decomposers. The quantity of abiotic materials like the minerals present at any given time in an ecosystem is termed as the standing state similar to the standing crop, which refers to the quantity of biotic components. In lakes and ponds, the producers are rooted or large floating plants and microscopic plants (phytoplankton), usually the algae. Components of an Ecosystem. It includes basic in-organic (soil, water, oxygen, calcium carbonates, phosphates etc.) Components of Ecosystem. 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. Green plants are the predominant producers; animals, the consumers; and fungi and bacteria, the decomposers. Biotic Components 2. This includes the distribution of energy in the environment. Share Your PPT File. The primary consumers in an ecosystem are herbivores, which feed directly on the producers (green plants). 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. The components of the ecosystem are divided into abiotic and biotic. However, whether large or small, rooted in the soil or floating in the water, all producers support an array of consumers and decomposers. The environmental system consists of biotic and abiotic components in a habitat. (160410111045). See our User Agreement and Privacy Policy. TOS4. Which organelle is known as “power house” of the cell? Abiotic Components: These are non-living thing components consist of carbon, hydrogen, sulphur, nitrogen and phosphorous etc. The various structural components of an ecosystem are classified under two main groups. 1. Or simply, we can say ecosystem functions relate to the structural components of an ecosystem (e.g. An ecosystem has a physical environment, or factors, biological components and interactions between them. Q.1 Describe different components of ecosystem in brief.4. The ecosystem is largely divided into two functional components; the Abiotic and Biotic. 2. Looks like you’ve clipped this slide to already. and organic compounds. 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. Share Your Word File The function of ecosystem is related to the energy flow, decomposition, nutrient cycling and major biomes. Disclaimer Copyright, Share Your Knowledge Some ecosystems may have the top carnivores like the lion and vulture, which are not killed or rarely killed and eaten by other animals. We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. 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. The materials are like water, minerals atmospheric gases, and salts. We observe that organisms living in any ecosystem are nowhere identical, but can be categorized into species. Therefore, animals are also busy in the process of organic production. 2) Organic compounds – Protein, Carbo-hydrates, Lipids – link abiotic to biotic aspects. 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. Based on this concept, the green plants are called primary producers and the heterotrophic organisms as the secondary producers. These are called the tertiary consumers. An ecosystem is also defined as a functional and structural unit of Ecology. 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. The components ofan ecosystem 4. The structural components of the ecosystem are producers, consumers, decomposers, gases, water, etc. Components of Ecosystem. Consumers are those living organisms that ingest other organisms and are, therefore, called heterotrophs. An ecosystem is a group or community composed of living and non-living things and their interactions with each other. Structure and Function of an Ecosystem: Each ecosystem has two main components: (1) Abiotic (2) Biotic (1) 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. are some examples of natural ecosystems whereas aquarium, park, crop-field etc. 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. Abiotic component. In the ocean, the rooted and floating algae are the producers. The Components Of Ecosystems4• The structural components of an ecosystem consist of nonliving arena and theliving organisms.• structural complexity on different components of the eco-system and ecosystem services. Clipping is a handy way to collect important slides you want to go back to later. The ecosystem of distinct terrestrial areas with climax plants and associated animals are known as biomass. What are the characters Mendel selected for his experiments on pea plant? Decomposers or the micro-consumers are also called the saprobes or saprophytes. They derive their food directly or indirectly from the producers or the green plants. Another important type of consumers is the bottom-living detritivores, which subsist on the rain of organic detritus from autotrophic layers above. Biotic component. They can be natural as well as artificial. 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 … 2 However, some ecosystems may lack one or another of the components. An ecosystem can be as big as an entire ocean or as small as a drop of water. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. The functional attributes of the ecosystem keep the components running together. No public clipboards found for this slide. Generally ecosystems consist of two basic components. (b) Heterotrophic component {heterotrophic = other nourishing, which utilizes, rearranges and decomposes the complex materials synthesized by the autotrophs. The vast majority of consumers are the animals. 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. 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. Our mission is to provide an online platform to help students to share notes in Biology. Grassland, pond, desert, forest, sea etc. 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. The organic components of an ecosystem are proteins, carbohydrates, lipids and amino acids, all of which are synthesized by the biota (flora and fauna) of an ecosystem and are reached to ecosystem as their wastes, dead remains, etc, The climate, tempe­rature, light, soil, etc., are other abiotic components of the eco­system. The abiotic component of the ecosystem refers to the physical environment or the non-living factors. 1. The most intense heterotrophic activity takes place where the organic matter accumulates in the soils and sediments.
