What Are Examples of Biotic Factors?

Good examples of biotic factors include plants, fungi and animals. Biotic factors are living things that affect or influence an ecosystem either positively or negatively.

These factors are divided into three categories: producers, consumers and decomposers. Producers, scientifically known as autotrophs, are biotic factors that convert energy into food. Plants are good examples of such factors since they convert energy from the sun into food, through photosynthesis.

Consumers, also known as heterotrophs, depend on producers for food. They also depend on other consumers for food, but this happens on rare occasions. Herbivorous animals are good examples of heterotrophs since they mostly feed on plants.

The main role of decomposers, alternatively known as detritivores, is to break down chemicals gathered from consumers and producers into simpler form. Bacteria and fungi are common decomposers. The chemical decomposition process takes place when the producers or consumers are dead.

For an ecosystem to be complete, biotic and abiotic factors have to be present. They depend on each other to make a complete food chain and life cycle. For instance, decomposition does not occur in the absence of producers or consumers. Most plants also grow healthily when decomposed matter from plants or animals is introduced into the soil.
