Across
  1. 1. nonliving parts of the environment
  2. 3. living or once living parts of the environment
  3. 6. all of the factors that a species needs to survive, stay healthy, and reproduce (ie food abiotic conditions and behavior)
  4. 8. combination of all the possible food chains within an ecosystem
  5. 10. an organism that only eats plants
  6. 14. a type of interaction in an ecosystem bc they fight for limited resources
  7. 15. environmental conditions that limit the growth, abundance, or distribution of an organism or a population of organisms in an ecosystem--causes competition between individuals in a species population
  8. 17. biggest level of organization--planet, earth, everything together
  9. 20. factors that decrease the population bc of the population density (ie limited food supply, disease, living space) (kselected affected more)
  10. 21. get their energy from nonliving resources (autotroph)
  11. 24. an organism that harbors a parasitic, a mutualistic, or a commensalist guest, the guest typically being provided with nourishment and shelter
  12. 26. one organism benefits, the other is unaffected
  13. 27. type of chart where something doubles or triples and goes up drammatically
  14. 28. two animals living in close association (mutualism, parasitism, commensalism)
  15. 29. species that are affected more by denstiy dependent factors
  16. 31. organisms that eat meat
  17. 33. all the living and nonliving factors in an environment
  18. 35. group of organisms of the same species living in the same place at the same time
Down
  1. 2. eat both meat and plants
  2. 4. an animal that is hunted and killed by another for food
  3. 5. factors that decrease the population that have nothing to do with the population (ie weather, temp, natural disaster) (rselected affected more)
  4. 7. species that are affected more by density independent factors
  5. 8. linear sequence of organisms showing energy flow and what organisms eat waht
  6. 9. both organisms benefit
  7. 11. when an organism moves from another place TO that place
  8. 12. feed on other organisms for energy (heterotrophs)
  9. 13. a process in which plants create food from sunlight
  10. 16. where an animal lives
  11. 18. any animal that hunts and kills another animal
  12. 19. capacity capacity of how many of a species the environment can hold
  13. 22. eat fungi and mushrooms and things that decompose from plants to soil
  14. 23. populations of different species interacting w each other
  15. 25. one organism benefits, the other is harmed
  16. 30. graphical model of energy flow in a community
  17. 32. a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding.
  18. 34. study of the interactions of organisms w each other and their environment
