An ecosystem is all the living and nonliving things that interact in an area. An organism's habitat is the place where it lives and gets what it needs to survive, like food, water, and shelter. Biotic factors are the living parts of an ecosystem like plants and animals. Abiotic factors are the nonliving parts like water and sunlight. A species is a group of organisms that can reproduce, a population is all the members of a species in an area, and a community is made up of all the populations living together. Ecology is the study of how living things interact with each other and their environment.
