What term refers to all individuals of a species living in the same area?

• A. Population
• B. Community
• C. Colony
• D. Guild

Answer: (A)

The concept being tested is how ecologists categorize groups of living organisms in a place. The term for all individuals of a single species living in the same area is a population. A population focuses on one species within a defined space, and scientists study its size, density, distribution, and growth over time.

In contrast, a community includes all living organisms in the area, across many species. A colony refers to a group of individuals of the same species living together, often in close association or a social unit, but not the broader idea of every member of that species in the area. A guild describes a group of species that use the same resource in a similar way, emphasizing ecological roles rather than geographic grouping.
