What Makes Up an Ecosystem?

  • An organism’s habitat is the physical place where it lives. It is usually a small part of an ecosystem.

  • A niche is an organism’s role within an ecosystem. The niche includes an organism’s use of the living and nonliving resources in the ecosystem.

    • Because organisms have many different niches, many different species can exist together.
