What is the term for a group of organisms of the same species living in the same area?

The correct term for a group of organisms of the same species living in the same area is "population." In ecology, a population specifically refers to all individuals of a particular species that share a common habitat and are capable of interbreeding. This concept is crucial for studying how species interact with their environment, how they grow and decline over time, and how they respond to ecological pressures such as predation, competition, and environmental changes.

In contrast, a community refers to different populations of various species that live together in a specific area, while an ecosystem encompasses both the living (biotic) and non-living (abiotic) components interacting in a particular environment. A biome is a much larger ecological classification based on climate, vegetation, and animal life, such as tropical rainforests or deserts. Understanding these terms helps clarify the hierarchy of ecological organization and the relationships between species and their environments.
