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

The term that describes a group of individuals belonging to the same species living in the same area is "population." In ecological terms, a population refers specifically to members of a single species that interact with one another in a defined geographical region. This concept is fundamental in ecology as it helps scientists study dynamics such as reproduction, mortality rates, and population density.

Understanding the distinction between this term and others is essential. A "community," for instance, encompasses different populations of various species interacting within a given area, whereas "biomass" refers to the total mass of living matter within a specific area and is not restricted to a single species. An "ecosystem" includes both the biological community and the physical environment, highlighting interactions between living organisms and their environment, which also extends beyond the scope of a single species. Hence, "population" is the most specific and correct term when discussing individuals of the same species in a particular area.
