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.
Other organisms, called heterotrophs, take in autotrophs as food to carry out functions necessary for their life. Thus, heterotrophs â all animals, almost all fungi, as well as most bacteria and protozoa â depend on autotrophs, or primary producers, for the energy and raw materials they need.Heterotrophs obtain energy by breaking down organic molecules (carbohydrates, fats, and proteins) obtained in food.Carnivorous organisms rely on autotrophs indirectly, as the nutrients obtained from their heterotroph prey come from autotrophs they have consumed.utotrophs can be photoautotrophs or chemoautotrophs. Phototrophs use light as an energy source, while chemotrophs utilize electron donors as a source of energy, whether from organic or inorganic sources; however in the case of autotrophs, these electron donors come from inorganic chemical sources.
