Green plants constitute -

(a) first trophic level

Food chain is link between different organisms with respect to direction of flow of energy.

The first ones in the food chain are green plants which are producers at first trophic level.

They make food by the process of photosynthesis and are autotrophic in nature.

Plants are eaten by herbivores which are second trophic level.

Third trophic level is the area of carnivores and omnivores.

Fourth trophic level returns the organic constituents back to soil and are known as decomposers.
