What defines a population in biological terms?

A population in biological terms is defined as a group of individuals of the same species that live in a specific area. This definition focuses on the shared characteristics of members of that group, including genetic similarity and the potential for interbreeding. Members of a population interact with one another, compete for resources, and form a breeding unit, which distinguishes them from individuals of different species or from different populations.

The concept of a population is crucial in studies of ecology and evolutionary biology, as it addresses dynamics such as population size, density, distribution, and genetic variation, which directly affect survival and reproduction. Understanding a population helps biologists assess how species interact with their environment and the factors that influence their growth and decline.
