Importance of the Nitrogen Cycle

Importance of the Nitrogen wheel aroundNitrogen cycle is the central to the biogeochemistry of the Earth, which occupies 79% within the air. Nitrogen is an essential element for deedss and animals to grow and to survive. (Soetan, Olaiya Oyewole, 2010). There are 7 atoms number of figure of N. The life time of reactive normality in atmosphere and in terrestrial are a few weeks and a few decades respectively. (Fowler et al., 2013) This study would be focusing on the normality cycle, homosexual beings activity and wallop on environment.Nitrogen sewernot be bio- routined directly, which needs to be switchred by variant unconscious process such as northward cycle include fixation, assimilation, ammonification, nitrification, denitrification and anaerobiotic ammonia oxidation. Nitrogen fixation is to turn atmospheric nitrogen into a usable fixed form for plants. (Mior, JWB(editor)2011) Assimilation is the process of how plants relieve nitrogen from soil. (Smil, V. 2000) Am monification is the process of converting organic nitrogen from expels waste to ammonium. Nitrification is the conversion of ammonium to nitrate. Denitrification is the process of turning nitrates to nitrogen grease-gun, which is the final stage of completing the nitrogen cycle. The biologic process of anaerobic ammonia oxidation is to convert nitrite and ammonia to molecular(a) nitrogen. (Nitrogen cycle, 2017). For instance, nitrogen gas would process nitrogen-fixing bacteria in soil or root nodules or lightning, hence to become nitrate compounds. Ammonia can also be converted to nitrates after being converted to ammonia(NH3) (Nitrogen fixation) by the Haber process and converted in the soil or break downcast and return nitrogen to the air. Proteins would be built up after the plants absorb nitrates from the soil and wait for being eaten by animals, and become animal protein. The nitrogen-bearing wastes in animal urine would become ammonia (process of decomposers or ammonificati on) and fend for into soil. Furthermore, the bead bodes of organisms would also being beak down to ammonia and back off into soil. (BBC, 2006)In addition, homophile activities would change the nitrogen cycle base on different factors. Nitrogen would append with the increases of fossil fuel combustion. Due to the process, would transfer fixed nitrogen from long-term geological reservoirs to the atmosphere. ( Vitousek, P, et al., 1997) Vitousek, P, et al. in 1997 state that human activities increased the quantity of organic carbon stored within terrestrial ecosystems deepen losses of biologic diversity, especially losses of plants adapted to efficient use of nitrogen, and losses of the animals and microorganisms that depend on them and aroused changes in the composition and functioning of estuarine and nearshore ecosystems, and contributed to long-term declines in coastal marine fisheries Eichner (1990), Schlesinger and Hartley (1992) state that human has impacts on atmosphere and the concentration of volatile NH3 in soils by the agricultural fertilisation increases, thus, increase the process of fixed nitrogen and the release more nitrogen gases from soils and groundwater.Nitrogen is a key element that controlling different facets of the earth. divergent level of available nitrogen would affect many original plant species and their predators. Therefore, combustion of fossil fuel and many other human activities that increase the level of nitrogen would have environment consequences. Nitrous oxide(N2O) are bestow to climate change. Nitrous oxide is naturally present in small quantities in the atmosphere, however, human activities are increasing the amount in the atmosphere. Nitrogen occupies a distinguished position on climate change mitigation and adaptation. Although nitrogen can cool the effect on climate change, however, the contribution of aerosols makes great carbon dioxide due to nitrogen fertilization. Furthermore, N2O is a powerful greenhouse gas that causes stratospheric ozone layer depletion. (The nitrogen cascade excess nitrogen in the environment. 2014) In conclusion, ecosystem have own adjustment function to maintain the conditions precedent of organism. However, human activities, such as fossil fuel combustion, increase the level of nitrogen, thus, cause the influence of biodiversity and damages of ecosystem. Chain reaction occur after a significant rise of biosphere N2 emissions, for instance greenhouse gases, accelerated losses of biological diversity and losses of plants adapted to efficient use of nitrogen. Due to human growing population, decreasing the fixation of nitrogen will be a difficult challenge situation in the future. One the other hand, serval ways that can stop the loss of nitrogen from farmland and cherish water courses, thus, contributes to plants eutrophication. This type of methods can contribute to the nitrogen-limited waters area. Furthermore, the improvements of the efficiency of fire foss il fuel can also reduce the emissions. The most important factor is to transfer knowledge to developing country.Reference listBBC. (2006, folk 15). GCSE Bitesize Nitrogen cycle.
