What term describes a group of organisms of the same species living in a particular area?

The correct answer is population, which refers specifically to a group of organisms of the same species that inhabit a particular area. A population can be characterized by various factors including its size, density, and the reproductive dynamics of its members. This term highlights the importance of location and species when studying how these organisms interact with each other and their environment.

In contrast, the other terms refer to broader concepts in ecology. A community includes multiple populations of different species that coexist in a specific area and interact with one another. An ecosystem encompasses both the living organisms (communities) and the physical environment (like soil, water, and climate) in which they exist. A biome represents a larger ecological category that encompasses multiple ecosystems sharing similar climate conditions and types of flora and fauna, such as deserts, forests, and grasslands. Understanding these distinctions is fundamental in studying ecological relationships and dynamics.
