  2. 8. Interaction in which one organism eats another
  3. 9. Living factors in the environment.
  4. 13. The struggle between organisms to survive in a habitat with limited resources
  5. 15. Biome a biome that has little or no plant life, long periods without rain, and extreme temperatures; usually found in hot climates
  6. 18. Interaction that helps both species involved
  7. 19. Animals hunted or caught for food
  8. 20. Non-living factors in an environment
  9. 21. plant life
  10. 24. symbol for the transfer of energy in a food web
  11. 25. An organism that eats only plants
  12. 26. a small or specialized habitat within a larger habitat
  13. 27. The branch of biology that deals with the relations of organisms to one another and to their physical environment.
  14. 30. Anything that has mass and takes up space
  15. 31. Interaction that helps one species while neither helping nor harming the other
  16. 32. a group of organisms of the same species populating a given area
  17. 34. An organism that lives in or on another organism; one who lives off another person
  18. 35. An organism that is a mix of algae and a fungus
  19. 36. The source of energy for plants
  20. 37. A group of ecosystems that share similar climates and organisms
  21. 39. organism that obtains energy by eating animals
  22. 40. The process by which plants and some other organisms capture the energy in sunlight and use it to make food.
Down
  1. 1. All the different populations that live together in an area
  2. 2. A type of close and long-term biological interaction between two different species. Commensalism, parasitism and mutualism are the three types.
  3. 3. Events that impact the ecosystem
  4. 4. An animal that hunts other animals for food
  5. 5. the natural home or environment of an animal, plant, or other organism.
  6. 7. Any living thing
  7. 10. Biomes on land (forests, taiga, tundra, etc.)
  8. 11. organism that obtains energy by eating both plants and animals
  9. 12. prefix meaning life
  10. 14. to make or become larger; to add to
  11. 16. Anything that has mass and takes up space
  12. 17. animal life
  13. 21. web. A diagram that shows the transfer of energy among the organisms in an ecosystem
  14. 22. A biome with many types of long grasses. Region has four seasons e.g. Canada.
  15. 23. to become smaller or less
  16. 28. Interaction in which two or more species require the same limited resources
  17. 29. Interaction that benefits one species (the parasite) that lives in or on the other (host). The host is usually harmed.
  18. 33. Ground that is permanently frozen-found in the tundra
  19. 38. A community of organisms and their abiotic environment
