  1. 1. restarts the cycle of succession, but not back to the beginning—soil and nutrients are still present.
  2. 4. uses the energy from light to carry out various cellular metabolic processes
  3. 10. a hierarchical level system in an ecosystem showing a flow of energy throughout the levels
  4. 13. an organism that cannot produce its own food, instead taking nutrition from other sources
  5. 16. an animal that eats both plants and animals
  6. 17. an organism that is unable to make its own food and gets energy from consuming other organisms
  7. 18. rain, snow, sleet, or hail that falls to the ground.

  1. 2. largely carnivores that feed on the primary consumers or herbivores. They are heterotrophs, specifically carnivores and omnivores.
  2. 3. make up the second trophic level. They are also called herbivores. They eat primary producers—plants or algae—and nothing else
  3. 5. when a new patch of land is created or exposed for the first time
  4. 6. an organism that produces complex organic compounds using carbon from simple substances such as carbon dioxide, generally using energy from light or inorganic chemical reactions.
  5. 7. an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
  6. 8. organisms that obtain energy through chemical process called chemosynthesis rather than by photosynthesis
  7. 9. those that eats the secondary consumers (large predators). For example, owls that eat snakes.
  8. 11. An animal that only eats other animals
  9. 12. an animal that only eats plants
  10. 14. anything non-loving in an ecosystem
  11. 15. all of the living things in an ecosystem
  12. 18. an organism that makes its own food
