  4. habitat • The place in which an animal lives

  5. ecosystem • A biological community of interacting organisms and their physical environment.

  6. sustainability • The capacity to endure. • In ecology, the word describes how biological systems remain diverse and productive over time.

  10. ecosystem • A smaller part of the biosphere consisting of the organisms and non-living features that interact in an area

  11. primary succession • the development of biotic (living) communities in a previously uninhabited and barren habitat with little or no soil

  12. secondary succession • The development of communities in an area that has been disturbed but still retains its topsoil, as in a burned-over area

  13. climax community • An ecological community in which populations of plants or animals remain stable and exist in balance with each other and their environment. • A climax community is the final stage of succession

  14. species • All organisms of the same kind that adapted to a particular set of resources (called a niche) in the environment
