Which term best describes all populations living in a given area?

• A. Population
• B. Community
• C. Species
• D. Ecosystem

Answer: (B)

All populations of different species living in a given area form a community because it represents the living organisms in that space as a whole and how they interact with each other. A single population is only one species, so it wouldn’t cover the other species present. A species refers to that specific group of organisms capable of interbreeding, not the whole assemblage. An ecosystem includes the physical environment and the processes that move energy and nutrients through the system, going beyond just the living organisms. So, the community best captures all the populations coexisting in the area.
