Biome

A biome describes in very general terms the climate and types of plants that are found in similar places around the world.

ECOSYSTEM

Within each biome (click to learn more about biomes) are many ecosystems. Inside an ecosystem, living and nonliving factors interact to form a stable system. An ecosystem is smaller than a biome and includes only organisms and their local environment.

Organism (Individual)

An organism is a single individual animal, plant, fungus, or other living thing. An organism plays a part in each level of the environment.

Community

A community is made up of the living components of the ecosystem. In a community, different plants, animals, and other organisms interact with each other.

Population

A population is a group of organisms of the same species that live in the same area.
