Which term refers to a group of individuals of the same species?

The term that refers to a group of individuals of the same species is "population." In ecological terms, a population specifically defines a group of organisms that belong to the same species and live in a particular area at the same time. This concept is key in ecology and biology as it helps in the study of species interactions, genetic variation, and evolutionary processes within a defined geographical boundary.

In contrast, a community encompasses multiple populations of different species that interact and coexist in the same habitat. An ecosystem refers to the complex network of interactions that include not just the living organisms (communities) but also the abiotic components (like air, water, and soil) in a given area. A biome is a broader term that describes large geographical areas characterized by specific climatic conditions, vegetation types, and ecosystems. Understanding these distinctions is crucial for studying ecological relationships and conservation efforts.
