Across
  1. 1. Close association between two or more species that live together
  2. 3. Biological community and all the nonliving factors that affect it
  3. 6. Scientific study of all the interrelationships between organisms and their environment
  4. 7. Organism that cannot make its own food and gets its nutrients and energy requirements by feeding on other organisms; also called a consumer
  5. 11. Heterotroph that consumes both plants and animals
  6. 12. Symbiotic relationship in which one organism benefits at the expense of another organism
  7. 15. Simplified model that shows a single path for energy flow through an ecosystem
  8. 16. Heterotroph that preys on other heterotrophs
  9. 17. All the interacting populations of different species that live in the same geographic location at the same time
  10. 19. Model that shows many interconnected food chains and pathways in which energy and matter flow through an ecosystem
  11. 21. Biotic or abiotic factor that restricts the number, distribution, or reproduction of a population within a community
  12. 22. Heterotroph that eats only plants
  13. 23. Heterotroph that decomposes organic material and returns the nutrients to soil, air, and water, making the nutrients available to other organisms
  14. 25. Group of organisms of the same species that occupy the same geographic area at the same time
  15. 26. Each step in a food chain or food web
Down
  1. 2. Relatively thin layer of Earth and its atmosphere that supports life
  2. 4. Act of one organism feeding on another organism
  3. 5. Symbiotic relationship in which both organisms benefit
  4. 8. The interrelationships between organisms and their environment
  5. 9. Physical area in which an organism lives
  6. 10. Role, or position, of an organism in its environment
  7. 13. Organism that captures energy from sunlight or inorganic substances to produce its own food; provides the foundation of the food supply for other organisms; also called a producer
  8. 14. Large group of ecosystems that share the same climate and have similar types of communities
  9. 17. Symbiotic relationship in which one organism benefits and the other organism is neither helped nor harmed
  10. 18. Any nonliving factor in an organism's environment, such as soil, water temperature, and light availability
  11. 20. Any living factor in an organism's environment
  12. 24. Organism's ability to survive biotic and abiotic factors
