16. In the Nitrogen Cycle the nitrifying blue green algae eaten by fish turns into decaying organic matter then into free nitrates, nitrites, and ammonia. The denitrifying bacteria then becomes nitrogen in the atmosphere by lightning. Then the nitrogen in the atmosphere gets taken up by plants and then by the animals eating the plants. The excretion and dead organic matter of the animals then turns the nitrogen back into the free nitrates, nitrites, and ammonia.
19. Commensalism: The bulculus Ibis walks alongside a grazing cow and eats the insects the cow stirs up from the ground.
20. Parasitism: Braconid wasps, insect larvae into tomato hornworms tissues, timing things such that just as they're ready to pupate, they have eaten up the whole insides of the hornworm, and it dies.
22. A drought has occurred in the Freshwater Wetland. If the drought caused the water to dry up completely then you will have most of the insects, fish, land animals, and plants die or move to another location. Some animals may be able to migrate there now that there isn’t much water. The water, carbon, nitrogen, and phosphorus cycles will all be messed up and will have to try to reform themselves.
23. After primary succession the biome floor will mostly be covered with moss or if there are little areas of standing water a lot of algae and insects laying their eggs in the standing puddles. The secondary succession will have the beginning stages of plants growing and some insects starting to reappear. Then the animals will slowly start to become alittle more present and some new species may come.Work Cited<br />Shearer CA and Raja HA (2010).
