Answers: Biotic Factors Biotic, meaning of or related to life, are living factors. Plants, animals, fungi, protist and bacteria are all biotic or living factors. Abiotic Factors Abiotic, meaning not alive, are nonliving factors that affect living organisms.
Biotic factors, as well as abiotic factors, have more to do with how those parts of an ecosystem affect one another than the specific living or non-living thing itself. Biotic factors in an ecosystem are the living things that affect other living things in that ecosystem. Competition, consumption, predation, parasitism, disease, even symbiosis are all ways a biotic factor could have an effect on the other creatures they encounter.
