  1. Envi-Sci Quiz Prep 10.4

  2. From • Energy Flow in Ecosystems Reading Notes

  3. What is the source of energy plants use to grow?

  4. THE SUN

  5. What is the process called whereby the plants convert the sun’s energy into food?

  6. PHOTOSYNTHISIS

  7. Where do animals get their energy to grow, move and reproduce?

  8. They eat the plants or other animals that ate plants

  9. SO, originally, where did the all the energy come from that the animals use?

  10. THE SUN

  11. What is a producer?

  12. PLANTS

  13. What is a consumer?

  14. ANIMALS

  15. What chemical source do some deep ocean producers use for energy?

  16. Thermal Vents

  17. What are decomposers?

  18. Fungus and bacteria that eat dead plants and animals.

  19. Producers are what tropic level?

  20. The bottom

  21. Herbivores are what tropic level?

  22. First level consumers

  23. Carnivores are what tropic level?

  24. Second (+)level consumers

  25. How does your body get the energy out of food?

  26. CELULAR RESPIRATION

  27. What is cellular respiration?

  28. The process cells use to oxidize food to extract it’s energy

  29. For what do you use most of the energy you obtained through cellular respiration?

  30. Most of the energy is used just to keep you alive and growing.

  31. What happens to the excess energy that you don’t use?

  32. It is stored as fat until you need it.

  33. How can we trace the transfer of energy through an ecosystem?

  34. Energy Pyramid

  35. What is a “food chain”?

  36. A simplified model of who eats what.

  37. How is energy lost at each trophic level?

  38. About 90% of the energy taken in is lost to the processes of cellular respiration and just keeping the organism alive

  39. How does energy loss affect the types of organisms at each increasing tropic level?

  40. Fewer individuals can be supported at each increasing level

  41. Drill • How do decomposers fit into the ecosystem’s energy flow?

  42. Decomposers can put some energy back into the system when they are eaten

  43. Drill • How do decomposers help the environment?

  44. They return nutrients to the soil, and clean up debris that could cause disease or fuel fires

  45. Why do large hunting animals have super large territories?

  46. They are at the top of the food and energy pyramid where the energy density is the lowest

  47. Food/Energy Pyramid

  48. REAL Food/Energy Pyramid90% energy loss each level

  49. Population Sampling Lab • How would the number of samples affect the results?

  50. More Samples = Better accuracy
