8. all the processes through which natural ecosystems help sustain life.
9. integrates different fields of biology to conserve biological diversity.
12. when a small population is prone to positive-feedback loops of inbreeding and genetic drift.
13. (minimum viable population), the minimal population size at which a species is able to sustain its numbers and survive.
14. the use of organisms (prokaryotes, fungi) to detoxify polluted ecosystems.
15. augmentation use of organisms to add essential materials to a degraded ecosystem.
16. based on the breeding potential of a population.

1. the absorption and re-radiation of the sun’s energy.
2. an extensive region that includes areas relatively undisturbed by humans surrounded by areas that have been changed by human activity.
3. small area with an exceptional concentration of endemic species and a large number of endangered and threatened species.
4. development that meets the needs of people today without limiting the ability of future generations to meet their needs.
5. species that humans move, intentionally or accidentally.
6. when accumulated toxins become concentrated in successive trophic levels.
7. a narrow strip or series of small clumps of habitat connecting isolated patches.
9. the amount of added nutrient, usually nitrogen or phosphorus, that can be absorbed by plants without damaging ecosystem integrity.
10. applies ecological principles to return ecosystems that have been damaged by human activity to their natural state.
11. a species that is in danger of extinction throughout all or significant portions of its range.
