Which term describes a group of different species living together in the same area?

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

Answer: (B)

A community is the assemblage of populations of different species living in the same area and interacting with one another. The idea centers on the living components in a specific locale—the variety of organisms and their relationships—within that place. A population refers to all individuals of one species in an area, so it doesn’t capture multiple species. An ecosystem includes both the living organisms and the physical environment, along with energy flow and nutrient cycles, making it a broader concept than a community. The biosphere is the global sum of all ecosystems, far more expansive. For example, a pond with fish, plants, insects, and bacteria represents a community because those diverse species share the space and interact in that habitat.
