Detailed explanation-1: -A population is a group of individuals of the same species that live in the same geographic area that interbreed with each other. Many species consist of multiple populations dispersed over a few to many geographic areas.

Detailed explanation-2: -Individuals make up a population; populations make up a species; multiple species and their interactions make up a community; and multiple species and their interactions make up ecosystems when you include the abiotic factors.

Detailed explanation-3: -Populations are groups of organisms of the same species living in the same area at the same time. They are described by characteristics that include: population size: the number of individuals in the population.

Detailed explanation-4: -If two populations belong to the same species then they do not have an impediment to reproduction and together they share in the larger evolutionary process of the single species of which both are a part.
