Ecosystem Dynamics

1. An animal lifeform that consumes both plants and animals
3. Influences on an ecosystem from non-living things or forces
6. An animal lifeform that only consumes plant life
7. The locations most likely to find a particular type of life form
10. A type of species whose presence determines the health of the ecosystem
13. This trophic level consumes both plants and animals
16. This trophic level predates on animals below it, but still has to be aware of its own predator(s)
17. Life forms that exist in every ecosystem whose job is to recycle matter
18. The number of different species inhabiting an ecosystem, a measure of ecosystem health
19. This trophic level feeds only on plants and transfers the captured energy directly into the ecosystem
20. Influences on an ecosystem from living things or forces
21. A life form with the ability to turn solar energy into chemical energy
22. The only global species

2. a geographic region defined by the connected life forms that inhabit the area
4. The chemical reaction producers use to convert sunlight into glucose
5. The chemical reaction used by life to extract energy from chemical bonds
8. This trophic level exerts a very strong top-down population control pressure on the others
9. A type of species artificially introduced to a foreign ecosystem, usually by humans
11. A diagram that shows the predator prey relationships, habitat, and trophic level of organisms within an ecosystem
12. An animal lifeform that only consumes other animals
14. The process of stalking and consuming another life form for sustenance
15. The direct struggle for habitat, water, food, mates, and survival
21. A very controversial crop being grown in rainforest ecosystems as an additive to western foods
