Population

What neighbors refer to when they talk about the dog population or the squirrel population in place, they are indirectly referring to the total number of dogs or squirrels in the place.

Each species of organism has its own population and a species refers to an assemblage of organisms that are capable of mating to produce fertile progenies.

Since dogs can only mate with dogs and squirrels with squirrels, each of them will form their own population within a community.
