Individual An individual is one organism.

Biological Population A group of individuals of the same species, living together in one place at one time, is called a biological population.

Species A species is a group of organisms who can successfully reproduce among themselves.

Biological Community A biological community is made up of all the populations that live in one area.

Habitat In every community, each species has a particular place where it lives, known as the habitat. {eg: cheetahs live in jungle}

Adaptation An adaptation is an inherited characteristic that helps an organism survive and reproduce in its environment.
