Answer 1

The structural component of an ecosystem may be classified under two main types: 1. Biotic components 2. Abiotic components Biotic components comprise the living organisms present in an ecosystem. These include plants, animals and micro-organisms (bacteria and fungi). The biotic component of an ecosystem has been classified into three groups: 1. Producers (green plants) 2. Macro consumers (usually animals) 3. Micro consumers or decomposers (organisms like bacteria and fungi). Abiotic components consist of the non-living components like light, temperature, water, oxygen,carbon, nitrogen and minerals. Various important abiotic factors have been classified as follows: 1. Climatic factors: These include light, temperature, precipitation, atmospheric humidity and wind. 2. Topographic factors: These include altitude, surface slope and exposure, etc. 3. Edaphic factors: These include soil and substratum.
