What are biotic factors?
Biotic factors are the living components of an ecosystem and are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores. Biotic factors in an ecosystem are simply living factors that have an effect on the said ecosystem.
Examples of biotic factors include any animals, plants, trees, grass, bacteria moss, or moulds which is a part of the ecosystem.
Grass as producers (autotrophs).
Mouse, deer, and owl as consumers (heterotrophs).
And earthworms as decomposers (detritivores).
