  9. What percent of energy is passed from one trophic level to the next?
  10. What do we called intertwined food relationships (food chains)?
  11. How does matter differ from energy in a food chain?
  12. Sketch the water cycle?
  13. What living things release carbon dioxide into the atmosphere?
  14. What percentage of energy is lost at each trophic level?
  15. In a food web, what trophic level supplies energy for all the other levels?
  16. According to the pyramid of numbers would there be more deer or mountain lions in an ecosystem?
  17. Would producers, herbivores or carnivores have the greatest biomass in an ecosystem?
  18. Are there more carnivores, consumers, omnivores or heterotrophs in an ecosystem?
  19. What happens to an ecosystem if the number of consumers is greater than the number of producers?
  20. What happens to the amount of energy available as you move up the pyramid of energy?
  21. What is a predator? What is a prey organism?
  22. Would the death of a food organism be disadvantageous to a parasite?
  23. What is another name for the biotic portion of an ecosystem?
  24. What is a habitat?
  25. Do algae (microscopic producer) or paramecia (microscopic consumer) or both produce oxygen?
  26. Do algae (microscopic producer) or paramecia (microscopic consumer) or both use oxygen?
  27. Do algae (microscopic producer) or paramecia (microscopic consumer) or both produce carbon dioxide?
  28. Do algae (microscopic producer) or paramecia (microscopic consumer) or both use carbon dioxide?

  30. What is a community?
  31. What do producers use nitrates for?
  32. Microscopic algae use carbon dioxide for making shells of calcium carbonate. When they die, they sink to the bottom of the ocean and form limestone. Will this carbon be recycled into the atmosphere?
  33. Where is most of the world nitrogen found?
  34. What is earth’s life supporting layer of air, soil and water called?
  35. What do we call a group of organisms of different species that live together?
  36. What is a population?
  37. Give an example of a population.
  38. What is an organism’s niche?
  39. During nitrification, ammonia is converted to what compound that can be used directly by producers?
  40. What do we call organisms at the first trophic level?
  41. A coyote is a producer, primary consumer or secondary consumer?
  42. What trophic level do crayfish, vultures, cockroaches, raccoons, rats and jackals belong to?
  43. What do we call intertwined food chains?
  44. As we move up the ecological pyramids from their base, what happens to the amount of energy, biomass and number of organisms?
  45. What trophic level is most abundant in a food chain?
  46. What trophic level is generally not shown in food chains and food webs?
  47. List three specific producers.
  48. I have a balanced aquarium in my back window of my room. Is it an ecosystem?
  49. Show a consumer-producer relationship. Ie name a specific consumer that eats a specific producer.
  50. What trophic level would a hawk belong to?
  51. What is competition?
  52. What force is the role of the atmosphere in the water cycle?
  53. Answer this one A and you will get it right.
  54. What type of organisms do all other organisms depend on for food?
  55. What would happen if there were no decomposers?
  56. Why do animals establish territories?
  57. What is mutualism, commensalisms and parasitism?

  59. Do short food chains or long food chains provide the most energy to the last organism in the food chain?
  60. Draw a food chain of 4 organisms.
