Document Summary

->atmospheric nitrogen-->n2 (gas)-->cannot use as animals or plants. ->fixation: taking gas nitrogen and making into form that can be used by organisms. ->nitrogen fixation take n2 form and turn it into ammonium (nh4) ->takes nitrogen gas and turns it into form that organisms can use. ->nh4-->nitrates (no3), and other forms of nitrogen molecules that have that form as well. ->through livestock, agriculture, fossil fuels, ocean, natural processes. ->effects of nitrogen as limiting nutrient in aquatic ecosystems. ->relative amounts of nitrogen relation to agriculture of plants and animals (fertilizers and other compounds use in agriculture) ->nitrogen pollution: the forms in the water such as nitrates and no2. ->nucleic acids, fertilizers, used to be important in soaps, phosphates. ->ground level, leads to pollution, respiratory diseases, etc. ->one idea to reduce carbon and ocean acidification-->dump iron in, remove carbon from system. ->eutrophication-->algae grows too well, consumers don"t eat all of it, decomposers come in, use up too much oxygen-->anoxia.
