2. The five levels of biological organization in ecology in order from largest to smallest are known as these.

3. What are: 1.Biosphere 2.Ecosystem 3.Community 4.Population 5.Organism?

4. Bufflegrass and cane toads are examples of this.

5. What is are invasive species.

6. Water is lost to the abiotic parts of the biosphere from the biotic parts by the process known as this.

7. What is transpiration?

8. This type of symbiosis occurs when one organism benefits and the other is neither harmed nor benefitted.

9. What is commensalism?

10. The two main ways atmospheric nitrogen is converted into a usable form.

11. What is nitrogen fixation and lightning?

12. The source of all energy in terrestrial ecosystems is located here.

13. What is the sun?

14. This diagram is also called this.

15. What is a food web?

16. This organism is a producer.

17. What is grass?

18. The third order consumer in this picture is this color.

19. What is gray?

20. The secondary consumers have this much usable energy.

21. What is 100 kcal?

22. A large group of ecosystems that share the same type of climax community is also known as this

23. What is a biome?

24. This graph illustrates this type of growth.

25. What is logistic?

26. This biome is characterized by a lack of trees and very cold temperatures throughout much of the year.

27. What is the tundra?

28. This biome is known to have frequent fires.

29. What is the chaparral?

30. The study of human population size is known as this.

31. What is demography?

32. When the last of a species dies the species is said to be this.

33. What is extinct?

34. The largest threat to biodiversity is this.

35. What is habitat loss?

36. Pollution is an example of this threat to biodiversity.

37. What is habitat degradation?

38. Protected strips of land that allow migration of species from one wilderness area to another are known as this.

39. What are habitat corridors?

40. Chloroflourocarbons destroy this.

41. What is ozone?

42. Any biotic or abiotic factor that limits an organism’s ability to survive is known as this.

43. What is a limiting factor?

44. Species in this area will be replaced by this type of succession.

45. What is secondary?

46. This aquatic ecosystem has no light.

47. What is benthic zone?

48. The passage of a highway through a wilderness area causes this.

49. What is habitat fragmentation?

51. The replacement of of one community by another as environmental conditions change.

52. What is succession?
