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
