Examples of biotic factors include any animals, plants, trees, grass, bacteria, moss, or molds that you might find in an ecosystem. In general, 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. Examples of biotic factors include: Grass as producers (autotrophs). Mouse, deer, and owl as consumers (heterotrophs). And earthworms as decomposers (detritivores).
