Which term describes a group of individuals of the same species living in one area?

• A. Population
• B. Community
• C. Ecosystem
• D. Limiting factor

Answer: (A)

In biology, when we describe a group of individuals of the same species living in one area, we call it a population. This term focuses on a single species and the number of its members interacting within a defined space, which is exactly what the prompt is asking for.

A community, by contrast, includes all living organisms in that area across different species, not just one species. An ecosystem adds the physical environment and the flows of energy and nutrients, combining biotic and abiotic factors. A limiting factor refers to a specific constraint that limits population growth, such as available food, space, or water—not a description of the group itself.

So the term that best fits “a group of individuals of the same species living in one area” is population.
