bio ecology test

4. feed on other organisms for energy (heterotrophs)
5. where an animal lives
8. all the living and nonliving factors in an environment
9. organisms that eat meat
12. two animals living in close association (mutualism, parasitism, commensalism)
17. get their energy from nonliving resources (autotroph)
18. an animal that is hunted and killed by another for food
20. graphical model of energy flow in a community
21. type of chart where something doubles or triples and goes up drammatically
23. combination of all the possible food chains within an ecosystem
24. eat both meat and plants
26. factors that decrease the population that have nothing to do with the population (ie weather, temp, natural disaster) (rselected affected more)
28. study of the interactions of organisms w each other and their environment
31. species that are affected more by density independent factors
34. both organisms benefit
35. 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
36. capacity capacity of how many of a species the environment can hold

1. an organism that harbors a parasitic, a mutualistic, or a commensalist guest, the guest typically being provided with nourishment and shelter
2. an organism that only eats plants
3. nonliving parts of the environment
6. factors that decrease the population bc of the population density (ie limited food supply, disease, living space) (kselected affected more)
7. group of organisms of the same species living in the same place at the same time
10. a process in which plants create food from sunlight
11. a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding.
13. living or once living parts of the environment
14. one organism benefits, the other is harmed
15. eat fungi and mushrooms and things that decompose from plants to soil
16. species that are affected more by denstiy dependent factors
19. any animal that hunts and kills another animal
22. one organism benefits, the other is unaffected
25. when an organism moves from another place TO that place
27. linear sequence of organisms showing energy flow and what organisms eat waht
29. a type of interaction in an ecosystem bc they fight for limited resources
30. biggest level of organization--planet, earth, everything together
32. populations of different species interacting w each other
33. all of the factors that a species needs to survive, stay healthy, and reproduce (ie food abiotic conditions and behavior)
