LIFE SCIENCE

Detailed explanation-1: -A community is all of the populations of different species that live in the same area and interact with one another. A community is composed of all of the biotic factors of an area. An ecosystem includes the living organisms (all the populations) in an area and the non-living aspects of the environment (Figure below).

Detailed explanation-2: -An organism is a single living thing, a population is all of the organisms of the same species in the same place at the same time, a community is all populations in the same place at the same time (all living things), and an ecosystem is the reactions between living and nonliving components in a given area.

Detailed explanation-3: -An ecological community is a group of actually or potentially interacting species living in the same location. Communities are bound together by a shared environment and a network of influence each species has on the other.
