8. 500 The type of symbiosis that occurs when one organism benefits and the other organism is neither benefited nor harmed What is commensalism Continue

9. 600 In the “Modeling Predation” lab, we modeled predation after an algal bloom and after a spawn. In our model, a __________was hunting for __________. What is heron, fish Continue

10. 700 Certain species of mites will live on the bodies of flies (mostly for transportation). The mite makes flight more difficult for the fly and also affects its aerial hunting ability. This interaction is _________ Continue What is parasitism

11. 800 Oxpeckers are birds that run over the backs of hippopotami and rhinoceroses. These birds rid their partners of injurious and annoying pests and in doing so obtain a ready supply of food. This is an example of _______________ What is mutualism Continue

12. 900 Humans have Demodicids (eyelash mites) that feast on oil secretions and dead skin. We don’t know they are there. This is an example of ___________. What is commensalism Continue

13. 1000 This is the difference between an ectoparasite and an endoparasite. What is endoparasites live within and ectoparasites live on the outside Continue

14. 100 What is habitat Continue All of the biotic and abiotic factors that make up the area where a species lives

15. 200 This is an example of both an abiotic and biotic factor in “your” environment: What is “1 living” and “1 nonliving”…answers vary Continue

16. 300 Species that occupy similar niches but live in different geographical regions What are ecological equivalents Continue

17. 400 When two species are competing for the same resources, one species will be better suited to the niche…and the other will be pushed into another niche or extinction What is competitive exclusion Continue

18. 500 This is what “niche partitioning” means: What dividing up natural resources, so that two species can “share” the niche Continue

19. 600 These are the three factors that make up an organism’s “ecological niche” What are 1)food, 2)abiotic conditions, 3)behavior Continue

20. 700 This is one reason why it might hurt biodiversity if you move an “exotic species” into a habitat it doesn’t currently occupy What is “it could better adapt to the niche or have no natural predators…it could drive native species out or to extinction [competitive exclusion] Continue

21. 800 Frog A lives in Madagascar and has the same nice as Frog B from South America. “This” is the reason why these frogs are NOT experiencing competitive exclusion. What is the frogs are not part of the SAME community (competing for same limited resources) Continue

22. 900 One of the factors that makes up an ecological niche; the time of day a species is active as well as where it reproduces. What is behavior Continue

23. 1000 An example of an outcome of competitive exclusion is _________evolution where selection for a specific physical trait allows one organism to be better adapted to survive in a different “part” of the niche. What is divergent Continue

24. 100 A measurement of the number of individuals living in a defined space What is population density Continue

25. 200 Individuals may live in this kind of “dispersion pattern” if they are territorial or compete for the same resources often. What is uniform dispersion Continue

26. 300 In order to gain protection or help each other out more readily in accessing food and other resources, individuals within a population may have this type of dispersion. What is “clumped dispersion” Continue

27. 400 The three-toed sloth is a solitary animal, and it has no competitors and few natural predators. It would most likely live in a __________ dispersion pattern What is random Continue

28. 500 Organisms like birds, small mammals and reptiles show survivorship roughly equal at all ages of an organism’s life. This is which “Type” of survivorship curve What is “Type 2” Continue

29. 600 Organisms like salmon have this type of survivorship What is Type III Continue

30. 700 This is the type of information a survivorship curve shows What is the number of surviving members in a population over time. Continue

31. 800 This is how population density and population dispersal are different What is population density measures the number of individuals in an area (not how they are grouped/dispersed) Continue

32. 900 This type of “intraspecific” interaction might cause uniform dispersion. What is competition for limited resources Continue

33. 1000 Scientists might infer “this” about a deer’s habitat if the density of the deer population decreases over a given time. What is that resources may be depleted or community may have changed due to arrival of a new predator Continue

34. 100 This is the type of growth that occurs when a population size increases dramatically over a period of time (producing a J-shaped curve) What is exponential growth Continue

35. 200 The movement of individuals out of a population into another population What is emigration (with an “e”) Continue

36. 300 The maximum number of individuals of a particular species that an environment can normally and consistently support What is carrying capacity Continue

37. 400 A dramatic decline of a population over a short period of time. What is a population crash Continue

38. 500 Parasitism and disease are examples of density _________limiting factors What is dependent Continue

39. 600 The “kind of factor” that has the greatest effect in keeping the population numbers LOW for any given species What is a limiting factor Continue

40. 700 Aspects of the environment that limit a population’s growth regardless of the density of the population What is a density independent limiting factor Continue

41. 800 An example of a density independent limiting factor What is unusual weather, natural disasters, and human activity Continue

42. 900 A population of algae in a pond is limited by the amount of sunlight that strikes the pond’s surface. Sunlight is an example of a density _____________factor. What is independent (unless the algae population becomes big enough to block the sunlight) Continue

43. 1000 A grasshopper feeds on meadow grasses. If a fire burns its field, resources are diminished, and carrying capacity is altered. This is one way carrying capacity could be increased for this population. What is (e.g. high rain  grasses flourish!) Continue

44. 100 This is the reason why shrubs and grasses are able to take root so quickly in secondary succession. What is there is soil already present Continue

45. 200 This type of succession occurs on a newly formed volcanic island (when no soil is present) What is primary succession Continue

46. 300 An example of a pioneer species. What are lichen, mosses, etc. Continue

47. 400 What a pioneer species’ job is… What is break down solid rock into soil Continue

48. 500 This is where succession is most likely to occur in an ocean. What is a coral reef. Continue

49. 600 Fire is important for secondary succession. This is fire’s role. What is fire helps return nutrients to the soil. Continue

50. 700 This is an example of the kind of tree that might first appear in primary succession. What is (LIST 1) cottonwoods, alders, or shrubs Continue

51. 800 These are two examples of types of events that might result in primary succession. What are glaciers, volcanoes, landslide, and strip mining. Continue

52. 900 This is the reason why primary succession will take much longer in arctic areas than tropical areas. What is soil takes longer to form ( because rock is covered with snow, the growing season is shorter, and cold temperatures slow growth and decomposition ) Continue

53. 1000 A lichen is an example of a pioneer species. But “this” is what a lichen has to do with “symbiosis” What is a lichen is two different species (algae conducts photosynthesis and algae collects water) Continue
