Across
  1. 3. An organism’s rank in the feeding hierarchy
  2. 8. An organism that captures energy from the sun or from chemicals and stores it, making energy available to the rest of the community
  3. 13. The process by which two species evolve in response to changes in each other
  4. 14. A sequence of DNA that codes for a particular trait
  5. 15. A relationship in which one species benefits and the other is unaffected
  6. 18. The disappearance of a species from Earth
  7. 19. Biological evolution that occurs by chance
  8. 22. A heritable trait that increases an individual’s fitness
  9. 23. An organism that relies on other organisms for energy and nutrients
  10. 26. A linear series of feeding relationships
  11. 27. An organism that is a primary consumer and eats plants
  12. 28. A visual map of feeding relationships and energy flow
  13. 29. A long-lasting and physically close relationship that benefits at least one organism
  14. 31. An animal that eats both plants and animals
  15. 33. The process of selection conducted under human direction
  16. 34. An organism that consumes nonliving organic matter
Down
  1. 1. The process of dividing a resource used in common by specializing in different ways
  2. 2. A species that has strong or wide-reaching impact on a community
  3. 4. Traits that improve an organism’s chance of survival are passed on more frequently to future generations than traits that do not
  4. 5. A relationship in which one organism benefits from, but harms, a host organism
  5. 6. The process by which primary producers use energy stored in chemical bonds to convert carbon dioxide and water into sugars
  6. 7. The ability to survive and reproduce under changing environmental conditions
  7. 9. A relationship in which two or more species benefit
  8. 10. The process by which new species are generated
  9. 11. The process by which organisms use oxygen to release the chemical energy of sugars
  10. 12. An organism’s use of resources and its functional role in a community

  12. 17. How reproductively successful an organism is in its environment
  13. 20. A consumer that kills and eats other animals
  14. 21. An organism that breaks down nonliving matter into simpler parts
  15. 24. The total amount of living tissue
  16. 25. The process by which primary producers use sunlight to convert carbon dioxide and water into sugars, releasing oxygen along the way
  17. 27. The interaction in which an animal feeds on a plant
  18. 30. The process by which an individual of one species—a predator—hunts, captures, kills, and consumes an individual of another species—the prey
  19. 32. A change over time
