Eutrophication affects species diversity and the overall health of the ecosystem in the body of water.

Eutrophication affects species diversity and the overall health of the ecosystem in the body of water.
1.)In any ecosystem, species interact on many levels. Population dynamics are a result of these various interactions and thepush of natural selection.For this discussion you must pick one of the following four relationships and analyze it according to the species interactions.Next determine how this interaction determines population dynamics. Once you have come up with an analysis of therelationship and its effects on population dynamics, summarize your work in your discussion post.Relationship1.The parasite Acanthocephalans, or spinyheadedworm, changes the behavior ofamphipods,2.Puccinia monoica and mustard plants of the genus Arabis,3.Cycles of abundance in snowshoe hares and their predators (lynx, goshawks, greathorned owls, and coyotes),4.Cicadas, especially the Magicicada species of cicadas, are great examples of aspecies increasing its rate of survival through predator satiation2.)Many bodies of water now undergo cultural eutrophication. This happens when the normal eutrophication process is spedup a hundred times by the actions of people.Pick one of the following and analyze how the process results in eutrophication of bodies of water. Make certain to covernutrient load, biological oxygen demand and dissolved oxygen levels and the results of each. Lastly, analyze how thiseutrophication affects species diversity and the overall health of the ecosystem in the body of water.1.Application of fertilizer to lawns2.Application of fertilizer to farm fields3.Failures in waste water treatment plants4.Logging3.)The local environments may change suddenly because of human or nonhumanevents. For example, there are fires in theWest every Spring, some started by people, some by lightning. What happens to these burned areas? The Spring may alsobring heavy floods to the Midwest, what happens to the land after the floods recede?Pick an area that was cleared by a natural or human activity such as fire, flood, logging, mining or volcanic eruption. Describethe steps of succession that occurred in the area you chose. Include the species or types of species that were the earliestinvaders and explain the characteristics that allowed these to invade first. When and how did each trophic level arrive
