Final answer:
The area inhabited by all individuals of a particular species is known as the population's geographic range.
Step-by-step explanation:
The area inhabited by all individuals of a particular species is known as the population's geographic range. Geographic range encompasses the entire area where the species is found, including all of the ecosystems they inhabit. This can be contrasted with the population density which is the number of individuals within a specific area or volume, and habitat, which is the environment in which a species normally lives or the location of a living organism. Lastly, an ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system.
