Question

Describe various components of ecosystem separately.

Answer 1

All ecosystems consist of two major components—biotic and abiotic. The biotic component is comprised the living organisms, whereas the abiotic component includes the physical (non-living) environment. But, both of these components interact very closely to exhibit a definite structural organization.

Answer 2

Answer:

Ecosystem is an interacting unit involving both living components and the non-living components of a region. Both of these components interact with each other functioning as a unit which is apparent in the processes of energy flow, nutrient cycling, productivity, decomposition in ecosystems such as grasslands, forest, ponds etc.

Ecosystems have two components, they are:

Abiotic components – These constitute the non-living components of an ecosystem such as temperature, light, water, wind, soil, chemical nutrients etc

Biotic components – They form the living component of an ecosystem which include biotic factors such as decomposer, consumers, and producers. Plants and some algae form the producers as they contain chlorophyll to synthesize their own food through the process of photosynthesis carried out in the presence of light, hence they are also referred to as transducers or converters. The consumers or heterotrophs are dependent on producers either directly (primary consumers) or indirectly (secondary consumers) while decomposers are constituted by the microbes in the ecosystem, such as fungi and bacteria. They form the largest population in the food chain as they derive their nutrition by disintegrating the residues of dead animals and plants.
