The term for all living organisms that inhabit a particular environment is "biotic factors." Biotic factors encompass a diverse range of life forms, including plants, animals, fungi, and microorganisms, all of which play vital roles in their ecosystems. These living components interact with one another and with the physical, non-living elements of the environment, such as air, water, and soil, which are categorized as abiotic factors.

This distinction is crucial in ecology, as biotic factors influence population dynamics, community structure, and ecological interactions like predation, competition, and symbiosis. Each organism's role within its environment contributes to the overall function and sustainability of the ecosystem. Understanding biotic factors helps ecologists assess the health and stability of ecological systems and manage conservation efforts effectively.
