Ecology gallery walk KEY
1. They recycle dead material back into
environment
2. Fungi and bacteria
3. Decomposers break down material that
need to be released back into the cycle and
nitrifying bacteria help convert nitrogen
compounds into different compounds
4. Bacteria
5. Prokaryotic
6. Eubacteria
7. Bacteria
8. A group of the same species in an area
9. All the interacting species in an area
10. Example: The American population of
humans and the community in America of
all the different species of life
11. Ecosystem is all the biotic and abiotic
factors together
12. Equal state or equilibrium. Organisms
response is always to maintain homeostasis
13. Ex. Humans sweating
14. Tolerance is the range they can live in,
optimum range is the best range to live in
15. Carrying capacity
16. Growth will decrease
17. Growth will increase
18. There will be less babies and more older
ones
19. There will be more babies/kids because the
population will grow
20. Afghanistan
21. Example: A forest fire burns down a forest,
so smaller grasses grow
22. It decreases biodiversity
23. Density independent
24. More stable because it can withstand
changes better
25. Less stable because it can easily be hurt by
change
26. The first one with more organisms because
it is more stable
27. organisms that aren’t native to that area
28. they can take over an ecosystem and hurt
native species
29. replacing a food source
30. a mouse gets 10% of cheese energy and
passes 10% of its energy onto the cat
31. grass->cheese->mouse->cat
32. pyramid with the above chain
33. 60 J
34. Increase
35. Decrease
36. Is not affected
37. Decrease
38. Increase
39. Decrease
40. Density independent
41. Density dependent
42. Density independent
43. Density dependent
44. Density independent
45. They stop or limit population growth and
can make a population change in a
community
46. Example: rabbits eating carrots
47. Example: nitrogen fixing bacteria on plant
roots
48. Example: wolf and bunny
49. Example: bird in a tree
50. Example: humans and mosquitos
51. Change of a population over time (plants
growing from small to big)
52. Breakdown of rock leads to soil which can
help bigger plants grow
53. It increases
54. Carbon is absorbed by plants, diffuses in to
ocean, is released by combustion, is
released by respiration…
55. Disrupting one part can negatively impact
the environment
56. Combustion
57. It is an atom needed to live, amino acids
58. Bacteria convert nitrogen into different
forms, decomposers break it down, plants
absorb…
59. Disruptions can negatively impact
environment, plants could all die
60. III, IV, I, II
61. Primary is on new area with no life (rock)
Secondary is in existing ecosystem with soil
62. Volcanic island vs, forest fire
63. G
64. Explain reasons F, H, and J are wrong
