  1. 5. (Autotroph) an organism that can make its own food by using the energy from the sun (photosynthesis) (ex. grass)
  2. 8. An organism that gets energy by breaking down the remains of dead organisms or animal wastes, and releases the nutrients to the environment (bacteria, sowbugs, worms, etc.)
  3. 9. all the populations of different species that live and interact in an area (living) (ex. sparrows, frogs, grasshoppers, squirrels)
  4. 10. An organisms that eats plant and animal material (ex. bear)
  5. 11. A complete living thing (ex. a mushroom)
  6. 12. An animal that is eaten by a predator
  7. 13. Feeding relationships among organisms in an ecosystem, made of many food chains
  8. 16. Eats another animal
  9. 20. Is any close relationship between different species, including mutualisms, commensalism, and parasitism. Often one organism lives in or on the other organism
  10. 22. A role the population plays in the ecosystem, such as how it gets food and interacts with other populations (ex. sharks eat fish) (producer, consumer, etc.)
  11. 24. An organism that eats only animal material (ex. lion)
Down
  1. 1. The path of energy transfer from producers to consumers
  2. 2. A group of individuals of the same species that live in the same place at the same time (ex. a group of sparrows)
  3. 3. Shows the direction that energy flows through an ecosystem and each level on the pyramid is called a trophic level
  4. 4. Anything that can limit the size of a population, including living and nonliving features of an ecosystem
  5. 6. (Heterotroph) an organism that eats other organisms to get energy (ex. a robin eats a worm)
  6. 7. An organism that eats only plant material (ex. bunny)
  7. 14. A community of organisms (living) and their (non-living) environment
  8. 15. A place where an organism usually lives
  9. 17. The study of how organisms interact with one another and their environment
  10. 18. Non-living part of an ecosystem (rainfall, sunlight, wind, soil, temperature, etc.)
  11. 19. Organisms that are closely related that can mate and produce fertile offspring (ex. male and female wolf)
  12. 21. Large geographic areas with similar climates and ecosystems, they can include such environment like the snowy tundra, the desert, or the very diverse tropical rainforest
  13. 23. A living part of an ecosystem (animals, plants, bacteria, etc.)
