Across
  1. 1. a phenomenon that occurs because the biomass at any given trophic level is produced from a much larger biomass ingested from the level below.
  2. 5. the range of different inherited traits within a species.
  3. 6. those that humans move internationally or accidentally from the species native locations to new geographical regions.
  4. 9. a result of large amounts of nutrients being released into a nutrient deficient water body which leads to excessive amounts of aquatic plant growth
  5. 16. a relatively small area with numerous endemic species and a large number of endangered and threatened species.
  6. 17. are those that are considered likely to become endangered in the near future.
  7. 18. a narrow strip or series of small clumps of habitat connecting otherwise isolated patches can be extremely important for conserving biodiversity.
  8. 20. the translocation of a species to a favorable habitat beyond its native range to protect the species from human-caused threats.
  9. 22. economic development that meets the needs of people today without limiting the ability pf future generations to meet their needs.
  10. 23. the variety of life in the world or in a particular habitat or ecosystem.
  11. 24. number of individuals in an idealized population that experience drift at the same rate as the population understudy.
  12. 25. defined as the variety of different habitats, communities and ecological processes.
  13. 26. refers generally to the human harvesting of wild organisms at rates exceeding the ability of populations of those species to rebound.
Down
  1. 2. warming that results when solar radiation is trapped by the atmosphere.
  2. 3. a treatment, procedure, or other action taken to prevent the loss of a species or population before its too late and extinction occurs.
  3. 4. the minimal population size at which a species is able to sustain its numbers. Hint: known as (MVP).
  4. 7. biodiversity islands in a sea of habitat degraded by human activity.
  5. 8. the amount of added nutrient, usually nitrogen or phosphorus that can be absorbed by plants without damaging ecosystem integrity.
  6. 10. an extensive region that includes areas relatively undisturbed by humans surrounded by areas that have been changed by human activity and are used for economic gain.
  7. 11. the fourth threat to biodiversity, global change, alters the fabric of Earth's ecosystems at regional to global scales.
  8. 12. an organic molecule that consists of nothing else but carbon and hydrogen atoms.
  9. 13. a small population is vunerable to inbreeding and genetic drift, which draw the population down to an ________, toward smaller and smaller population size until no individuals survive.
  10. 14. services encompass all the processes through which natural ecosystems purify our air and water.
  11. 15. integrates ecology, physiology, molecular biology, genetics, and evolutionary biology to conserve biological diversity at all levels.
  12. 19. on that is "in danger of extinction throughout all or a significant portion of its range.
  13. 21. alteration or destruction of a habitat, some examples being agriculture, urban development, forestry, mining, and pollution.
