Since these individuals are of the same species, they usually occupy the same niche in the ecosystem with similar habits and habitats. Usually, the individuals in a certain population do interbreed in order to maintain the population size that ensures successful future generations, and their kind is saved.

Community, also called biological community, in biology, an interacting group of various species in a common location. An example would be Since it consists of many different populations, there are many habitats as well as many ecological niches.
