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). To further understand the term biotic factors, it's helpful to look at the meaning of the terms biotic and abiotic. Biotic means pertains to life.
 These reduced carbon compounds can be used as an energy source by  the autotroph and provide the energy in food consumed by  heterotrophs. More than 95% of all organisms are heterotrophic.[2]   A heterotroph is an organism that requires organic  substrates to get its carbon for growth and development.A  heterotroph is known as a consumer in the food chain. Contrast with autotrophs which use inorganic carbon dioxide or  bicarbonate as sole carbon source. All animals are heterotrophic,  as well as fungi and many bacteria.These reduced carbon compounds can be used as an energy source by  the autotroph and provide the energy in food consumed by  heterotrophs.
