2. This level of organization contains organisms that can produce fertile offspring and live in a defined area

3. Population

4. These are the levels of nutrition in a food chain.

5. Trophic levels

6. This is the level of organization containing groups of several species in an area.

7. Community

8. Several ecosystems with similar communities and same climate make up this.

9. A biome

10. These organisms are likely at the top of the food chain, yet do not hunt and kill.

11. Scavengers

12. These organisms can make their own food from sun energy or chemicals.

13. Autotrophs

14. These organisms feed upon plants and animals

15. Omnivores

16. An ecosystem contains 34,640 Calories at the bottom trophic level. How many Calories are available at the third trophic level?

17. 346.4 Calories

18. These organisms are at the first trophic level

19. Producers/ Autotrophs

20. Theoretically, a food chain could have infinite trophic levels. Realistically, why can’t it?

21. If only 10% is passed up to the next level, so little energy would get to those high trophic levels that they would be required to eat too much biomass to be satisfied (they would never stop eating).

22. Water enters the atmosphere through these two processes

23. Evaporation and transpiration

24. Organisms need nutrients in order to do this

25. Carry out life processes

26. Nitrogen is made into a form that plants can take in by this organism

27. bacteria

28. How does carbon enter the atmosphere?

29. exhalation of organisms burning of fossil fuels

30. This nutrients is essential for nucleic acids (DNA) and it never enters the atmoshpere.

31. Phosphorus

32. What’s humus?

33. Layer in the soil made of dead organic matter

34. Over ½ of Earth’s species live in which biome?

35. Rainforest

36. True or false – energy is recycled through the environment.

37. False

38. What molecule is present in organic matter?

39. carbon

40. These two biomes receive the least amount of precipitation annually

41. Tundra and desert

42. This term refers to two organisms of a different kind living closely where one benefits and the other is neither helped nor harmed

43. commensalism

44. This term refers to two organisms of a different species living closely

45. Symbiosis

46. What’s the difference between parasites & predators?

47. Predators kill, parasites don’t

48. After a fire, the steps to rebuilding a community here is described as this.

49. Secondary succession

50. There are tiny unicellular organisms called zooflagellates living in the intestines of termites allowing them to digest cellulose from wood. What kind of relationship is described here?

51. mutualism
