Examples of Biotic Factors

Biotic factors are the living components of an ecosystem. They are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores.

Producers

Producers, also called autotrophs, convert energy into food, some using photosynthesis. Here are examples of producers:
