Across
  1. 2. consume detritus
  2. 3. a relationship in which two or more species benefit
  3. 4. conversion of sunlight, CO2, and water to sugar and oxygen.
  4. 8. a relationship in which one organisms depends on another for nourishment or some other benefit while the other is harmed.
  5. 10. organisms using the shared resource in different ways
  6. 11. an organisms role within its community
  7. 16. a species that has strong or wide-reaching impact on a community.
  8. 20. consumers that eat animals
  9. 21. a long-lasting and physically close relationship in which at least one organism benefits
  10. 24. describes how reproducibly successful an organism is in its environment
  11. 25. the process by which an individual of one species hunts, captures, kills, and consumes another.
  12. 27. break down nonliving matter into simpler parts that can be reused by producers
  13. 32. process by which traits that improve an organisms chances of survival and reproduction are passed on more frequently
  14. 33. process by which new species are generated
  15. 34. biological evolution that occurs by chance
  16. 35. total amount of living tissue in a trophic level
Down
  1. 1. conversion of hydrogen sulfide, CO2, and water into sugars.
  2. 5. consumers that eat plants
  3. 6. eat both plants and animals
  4. 7. rank in a feeding hierarchy
  5. 9. process by which organisms use oxygen to release the chemical energy of sugars such as glucose, releasing CO2 and water as byproducts.
  6. 12. the process by which two species evolve in response to changes in each other.
  7. 13. the ability to survive and reproduce under changing environmental conditions
  8. 14. an interaction in which an animal feeds on a plant
  9. 15. a relationship in which one species benefits and the other is unaffected.
  10. 17. the disappearance of a species from Earth
  11. 18. change over time
  12. 19. process of selection of desired traits for breeding
  13. 22. capture energy from the sun(autotrophs)
  14. 23. a sequence of DNA that codes for a particular trait
  15. 26. linear series of feeding relationships
  16. 28. rely on other organisms for nutrients(heterotrophs)
  17. 29. a map of feeding relationships and energy flow in a community.
  18. 30. a heritable trait that increases an individuals fitness
  19. 31. changes in DNA, give rise genetic variations among individuals
