Across
  1. 5. The type of symbiosis in which one partner, the parasite, derives benefit from the other, the host
  2. 7. The sharing of resources by specialization
  3. 9. Organisms that feed on dead organic material, especially plant detritus
  4. 12. The steps of transfer of energy from primary producers through consumers
  5. 13. The change in species composition, structure, or architecture through time
  6. 16. A type of symbiosis in which one species obtains shelter, food, or other benefits without affecting the host
  7. 18. The process in which one species evolves in response to another
  8. 19. All of the interconnecting feeding relationships in a community
  9. 20. The type of symbiosis in which both partners benefit from the relationship
  10. 21. Autotrophs
  11. 22. Individuals of the same kind that cannot breed with those of other kinds
  12. 23. A community or communities plus the physical environment, interacting in a large, more or less self-contained area
Down
  1. 1. A species on which other species in an ecosystem largely depend, if it were removed the ecosystem would change drastically
  2. 2. A mechanism of evolutionary change that results when individuals that are better adapted than others in meeting the challenges of the environment produce more offspring
  3. 3. A living component of the environment
  4. 4. The natural environment where an organism lives
  5. 6. A non-living component of the environment (physical or chemical)
  6. 8. Each of the steps in a food chain
  7. 10. The study of the interactions between organisms and their environment
  8. 11. The elimination of one species by another as a result of competition
  9. 14. A place that is particularly appropriate for something, due to being very specific and different from others
  10. 15. The variety of life in the world or in a particular habitat or ecosystem
  11. 16. Heterotrophs
  12. 17. Organisms that break down dead organic matter into smaller molecules
