The nitrogen cycle is a natural cycle that moves nitrogen through different compounds in the ecosystem Amonification The nitrogen cycle is important because all organisms require nitrogen in order to live. The US National Library of Medicine reprinted a study by Scott Fields that concludes humans inject nitrogen compounds into the air in ever increasing quantities, causing serious impacts on biodiversity, human health, water quality, global warming and also the rate of population growth in developing nations. Humans also affect the nitrogen cycle through the emissions of large quantities of NOx gases to the atmosphere. Human impact on the nitrogen cycle is diverse. Burning fossil fuels results in a change in carbon storage, thus affecting the nitrogen cycle and other vital processes. Similar to the carbon or oxygen cycle, the nitrogen cycle is critical to life. One of the key components of the nitrogen cycle is Nitric Oxide (NO) which is small and rapidly permeates cell membranes and aqueous solutions. Humans are greatly impacting the nitrogen cycle. How does the human impact of fertilizers impact the nitrogen cycle? Lakes are clogged with aquatic … Plants require nitrogen to live, so plants in general depend on the nitrogen cycle and are a crucial part of it. Fossil fuel combustion releases nitric oxides and combines with other elements in the air to form smog and acid rain. The natural amount of carbon dioxide exhaled by humans is used by plants and vegetation to produce necessary oxygen. The use of fertilizers affect the nitrogen cycle because fertilizers and nitrogen-fixing crops can be used to replace nitrogen in the soil. In order to move through the different parts of the cycle, nitrogen must change forms. Retrieved 4 October 2016, from http://science.jrank.org/pages/4692/Nitrogen-Cycle-Humans-nitrogen-cycle.html. It also enters coastal marine systems near the shore and causes anoxia, which means no oxygen, and hypoxia, which means low oxygen. Humans impact the nitrogen cycle primarily through fertilizer use. As it is also highly reactive, it gets depleted easily within the body and its range is relatively short. Although nitrogen is the most abundant element in the air, most organisms cannot use the nitrogen in the atmosphere. Perhaps the best evidence for this perturbation comes from air trapped in layers of quasipermanent ice in the Arctic and the Antarctic. It adds nitrogen to terrestrial ecosystems and leads to nutrient imbalance in trees, a decline in biodiversity, and changes in the health of forests. Describe 5 ways in which humans may intervene in the nitrogen cycle and the effects of these interventions. For example, if an organism receives too much, or not enough nitrogen, the In this way, changes in nutrient supply will affect the entire food chain.
