What defines a population in biological terms?

In biological terms, a population is defined as a group of individuals of the same species that occupy a specific area and are capable of interbreeding. This definition emphasizes the importance of genetic exchange among the individuals within the group, which is crucial for the continuation of the species and the maintenance of genetic diversity. Members of a population interact with one another, share a habitat, and compete for resources, which can influence their survival and reproduction.

The concept of a population is fundamental in ecology and evolutionary biology, as it allows scientists to study how groups of the same species interact with their environment and with each other. Understanding population dynamics is essential for conservation efforts, wildlife management, and studying evolutionary processes within species.

In contrast, the other options highlight different ecological concepts. For example, a group of different species implies a community rather than a population, and a collection of organisms in a specific habitat does not specify that those organisms are from the same species or can interbreed. Meanwhile, a community involves multiple populations living in the same area, sharing resources but defined by their interactions among different species rather than within a single species.
