  7. Which of the descriptions is correct?

  8. The lowest level of environmental complexity that includes living and nonliving factors

  9. Plants are 1. 2.

  10. 1. • Plants, some bacteria and some protists • Bacteria only • Requires sunlight • Doesn’t require sunlight • Makes carbohydrates • Makes oxygen • Uses hydrogen sulfide • Hydrothermal vent communities in abyss • phytoplankton in open ocean • Photosynthesis • Chemosynthesis 2.

  11. How do most primary producers make their own food?

  12. Which of the following organisms does NOTrequire sunlight to live?

  13. Compared to land, the open oceans

  14. In which way are plants in a sunny mountain meadow and sulfur bacteria in a deep-sea volcanic vent alike?

  15. The algae at the beginning of this food chain are

  16. Phytoplankton • zooplankton Producer Consumer Autotroph Heterotroph Drift in water Animal like Plant like

  17. herbivores • carnivores • omnivores • detritivores • decomposers • Meat eater • Plant eater • Eat meat and plants • Eat decaying particles • Decay dead organisms Longer intestine More surface area on teeth Extra chambers in digestive tract Sharper teeth

  18. How much energy is passed on to the next step in the food chain? WHY??

  19. Biomass Numbers Energy

  20. Primary producer Primary consumer Secondary consumer Tertiary consumer What happens to the number of frogs when the shrew population decreases? Why??? 1st trophic level 2nd trophic level 3rd trophic level 4th trophic level

  21. How do most primary producers make their own food?

  22. What would happen if the population of the bird species shown in the ecosystem were to suddenly decrease?

  23. What organisms are found in the climax community for this ecosystem?

  24. Corn planted in a field that has been previously planted with legumes and then plowed under is likely to be

  25. All the interconnected feeding relationships in an ecosystem make up a food

  26. The total amount of living tissue within a given trophic level is called the

  27. What animals eat both producers and consumers?

  28. What is the term for each step in the transfer of energy and matter within a food web?

  29. What are the three kinds of ecological pyramids?

  30. Only 10 percent of the energy stored in an organism can be passed on to the next trophic level. Of the remaining energy, some is used for the organism’s life processes, and the rest is

  31. A word that means the same thing as consumer is

  32. Matter can recycle through the biosphere because

  33. The repeated movement of water between Earth’s surface and the atmosphere is called

  34. 2. 1. 9. 8. 3. 4. 5. 6. 7.

  35. Carbon cycles through the biosphere in all of the following processes EXCEPT

  36. Which part of the water cycle is a biological process?

  37. Nitrogen fixation is carried out primarily by

  38. Which of the following has a direct role in the nitrogen cycle?

  39. Organisms need nutrients in order to

  40. The movements of energy and nutrients through living systems are different because

  41. Biogeochemical cycling ensures that

  42. What can happen immediately after a lake receives a large input of a limiting nutrient?

  43. Why can’t the producers in some ecosystems make an unlimited supply of organic material?

  44. Animals that get energy by eating the carcasses of other animals that have been killed by predators or have died of natural causes are called

  45. Phosphorus is very important for living things because living organisms need phosphorus to

  46. 2. 1. 7. 4. 6. 5. 8. 9. 3.

  47. Each of the following is an abiotic factor in the environment EXCEPT

  48. Which is a biotic factor that affects the size of a population in a specific ecosystem?

  49. During a long period when there is no rainfall, a mountain lion may temporarily leave its usual hunting territory to drink from a farm pond. This behavior is due to
