  2. 5. Autotrophs capture energy and use it to make organic molecules
  3. 7. The interrelated food chains in an ecosystem
  4. 8. These are consumers that feed on waste, fallen leaves, and animal waste
  5. 12. Ecologist refer to this quality as interconnectedness or ___________.
  6. 14. The movement of phosphorus from the environment to organisms and then back to the environment
  7. 18. These break down complex complex molecules, ex. mushrooms, fungi
  8. 20. Soil bacteria take up ammonium and oxidize it into nitrites,NO2-, and nitrates,NO3-, in this process
  9. 23. Ecologist refer to the organic material that has been produced in an ecosystem
  10. 24. The specific role, or way of life, of a species within it's environment
  11. 25. Ecologist often measure the rate at which biomass accumulates
  12. 28. The process by which watger evaporates from the leaves of plants in terrestrial ecosystems
  13. 29. Includes all the members of a species that live in one place at one time
  14. 31. The complex pathway that nitrogen follows in an ecosystem
  15. 33. Most organisms rely on this to transform nitrogen gas into a useable form
  16. 34. Some organisms use this process to adjust their tolerance to abiotic factors
  17. 37. This indicates the organisms position in a sequence of energy transfers
  18. 39. These eat both producers and consumers
  19. 40. The biosphere is composed of smaller units known as these
  20. 41. The place where an organism lives

  6. 10. Bacteria carry out _______ in which they use energy stored in inorganic molecules to produce carbohydrates
  7. 11. Substances that can pass between the living and non-living worlds
  8. 13. One way ecologist deal with complexity of ecology is to use _______ ______.
  9. 15. The process in which decomposers break down materials and release the nitrogen they contain as ammonia, N3, which in soil becomes ammonium, N4+
  10. 16. The process of converting N2 gas to nitrate
  11. 17. The movement of water between various reservoirs
  12. 19. The rate at which producers in an ecosystem capture the energy of sunlight by producing organic compounds
  13. 21. These eat other consumers
  14. 22. This process returns nitrogen to the atmosphere
  15. 26. The non-living factors of an environment
  16. 27. A longer-term strategy to enter a state of reduced activity
  17. 30. A strategy to move to a more favorable environment
  18. 32. The living components of the environment
  19. 35. Photosynthesis and cellular respiration form the basis of the ____ ____
