Detailed explanation-1: -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). An ecosystem is made of the biotic and abiotic factors in an area.
Detailed explanation-2: -Community ecology focuses on the processes driving interactions between differing species and their overall consequences. Ecosystem ecology studies all organismal, population, and community components of an area, as well as the non-living counterparts.
Detailed explanation-3: -The concepts of ecosystem and community are closely related-the difference is that an ecosystem includes the physical environment, while a community does not. In other words, a community is the biotic, or living, component of an ecosystem.
Detailed explanation-4: -The biotic factors refer to all the living beings present in an ecosystem, and the abiotic factors refer to all the non-living components like physical conditions (temperature, pH, humidity, salinity, sunlight, etc.) and chemical agents (different gases and mineral nutrients present in the air, water, soil, etc.)
Detailed explanation-5: -An ecosystem includes both living (biotic) and non-living (abiotic) components. In a community, interactions happen only between living organisms or biotic components. In an ecosystem, the interactions happen both between living components and living and nonliving components.
