Detailed explanation-1: -Since this definition mentions organisms, Population logically has to include biotic factors. The definition also mentions only organisms interacting with each other, no non-living things, thereby precluding any abiotic factors. Therefore, a Population only includes biotic factors.
Detailed explanation-2: -Biotic factors include interactions between organisms, like disease, predation, parasitism, and competition among species or within a single species. In addition, living organisms themselves are biotic factors. They fall into three main categories: producers, consumers, and decomposers.
Detailed explanation-3: -A community is all of the populations of different species that live in the same area and interact with one another. Which levels of ecosystem include only biotic factors? Populations and communities are levels of ecological organization that contain only biotic factors (living things).
