Every ecosystem has two components, namely, biotic components and abiotic components. Biotic components refer to all living organisms in an ecology while abiotically refers to the non-living things. Biotic and abiotic factors are two main categories of elements in an ecosystem : biotic factors are the living components, while abiotic factors are the non-living components that influence the environment. Learn the definitions, examples and differences of biotic and abiotic factors in an ecosystem. Biotic factors are the living organisms, while abiotic factors are the non-living physical and chemical components that affect the survival and reproduction of biotic factors. Understanding the difference between biotic and abiotic factors is essential for grasping how ecosystems function. Biotic factors encompass all living organisms and their interactions, while abiotic factors comprise the non-living physical and chemical components of the environment.
