Biology

4. A species that is in immediate danger of becoming extinct throughout all or most of its range.
6. The range of different inherited traits (DNA) within a single species or population.
7. A species that no longer exists in a specific geographic area it once inhabited, though it still exists elsewhere.
10. The continuous, low-level rate of species loss that occurs naturally over long periods of time.
11. The application of ecological knowledge to balance the needs of wildlife populations with the needs of people.
13. A species that is native to and naturally found in only one specific geographic location.
14. A multidisciplinary science focused on protecting biodiversity and preventing the loss of species.
15. An organism whose presence, absence, or health provides information about the overall quality of its environment.
16. The variety of habitats, communities, and ecological processes within a biosphere.

1. A species that is likely to become endangered in the foreseeable future.
2. The unsustainable harvesting of a renewable resource, often leading to a population collapse.
3. The total number of different species found in a specific community or ecosystem.
5. The total variety of life on Earth at all its levels, from genes to ecosystems.
8. An event in which a large percentage of all living species become extinct in a relatively short geological timeframe.
9. The study and practice of renewing and assisting the recovery of degraded or destroyed ecosystems.
12. A group of similar organisms capable of interbreeding and producing fertile offspring.
