Biotic and abiotic are terms commonly used in ecology to describe the living and non-living components of the system.

Biotic components of an ecosystem represent all the living beings in that particular ecosystem. The examples of biotic factors are animals, plants, microorganisms (such as bacteria, fungi, and the like). The biotic factors of an ecosystem are defined as the living things that directly or indirectly affect the life of organisms. These may include interactions, waste, parasitism, and such.

Abiotic or non-biotic components of an ecosystem represent all the non-living things that affect the ecosystem. The examples of abiotic components are water, air, minerals, light, humidity, temperature, wind, and more. These components influence the ability of a biotic component to survive and prosper and may limit its population in a given ecosystem.

Together, the biotic and abiotic components create an ecosystem.
