A group of organisms, plants, and animals living together and functioning together in their environment is called an ecosystem. An environment is all of the living and nonliving things with which an organism interacts. When living or nonliving things are interdependent that means they depend on each other.

All the living things such as plants and animals within an environment are called the biotic factors. All of the nonliving things in an environment like soil, light and temperature are called abiotic factors. Ecology is the science of the relationship between living things with one another and their environment.

The different living things that live together in an ecosystem are called a community. A population is made up of each of the kind of living thing or species inside a community. A species is each different kind of plant or animal. There can be many different habitats found in any ecosystem.

A habitat is a place that a population of an ecosystem lives in. Habitats supply the food, water, temperature, oxygen, and minerals needed by the organisms. If the organisms don’t have what they need in their habitat, then they will move to another one or they could die.

If a habitat is put in danger by changes to the habitat or within the community, and the conditions do not improve, then a habitat or its population could become extinct.
