Across
- 2. large group of ecosystems that shares the same type of climax community
- 4. Anything that limits an organism’s ability to live in a particular environment
- 5. a stable community formed after primary or secondary succession once little or no change occurs
- 7. Water is constantly moving between the atmosphere & Earth.
- 8. make their own food
- 11. The atmosphere is the main reservoir of nitrogen; it also cycles through the soil and tissues of living organisms.
- 12. An area where an organism lives
- 14. one organism benefits and the other is neither helped nor harmed
- 16. Phosphorus in biosphere cycles among the land, ocean sediments and living organisms
- 17. break down wastes organic matter (dead organisms) and return them to the ecosystem
- 18. Autotrophs that capture chemical energy since they live in places without sunlight
- 19. Process used by autotrophs to make food energy from the sun

- 31. organisms that seek out and eat other organisms
- 32. All strategies and adaptations a species uses in its environment
Down
- 1. both species benefit from relationship
- 2. Elements, compounds, and other forms of matter are passed from one organism to another and from one part of the biosphere to another
- 3. The process of gradual, natural, change and species replacement that takes place in the communities of an ecosystem over time.
- 6. Organisms that use sunlight or energy stored in chemical compounds to make food
- 9. cycle of carbon in the environment
