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

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

Answer: (A)

A population refers to the group of individuals belonging to the same species that inhabit a particular area. This term focuses on one species in a defined space, which is why it fits the idea of “a group of individuals of the same species living in the same area.” A community, in contrast, includes all living organisms in that area—many species together. An ecosystem adds the interactions between those organisms and the nonliving environment, like water, soil, and climate. A biome is a much larger geographic area characterized by a dominant climate and associated life forms. For example, a population would be all zebras in a savanna, a community would include zebras, gazelles, and trees in that same savanna, an ecosystem would consider how those organisms interact with rainfall and soil, and a biome would describe the broader savanna region across a continent.
