bio ecology test
Across
- 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
Down
- 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)
