Nitrogen Cycle Essay Examples

Seven biogeochemical cycles of carbon and nitrogen circulation carbon cycle, hydrogen circulation, nitrogen circulation, oxygen circulation, phosphorus circulation, sulfur circulation, and water circulation are important for the dynamics of the Earth system. All of these are related, mainly due to the carbon cycle change and the nitrogen cycle, which is not so much but promotes the climate change process today. The global warming potential of greenhouse gases containing these two elements is estimated to be 72% carbon dioxide, 18% carbon methane, 9% nitrous oxide, and 1% other carbonaceous gas It will be.

Nitrogen circulation is an important cycle for the atmosphere. Nitrogen is an important constituent of biomolecules such as proteins and nucleic acids, making nitrogen essential to all creatures. Nitrogen accounts for 78% of the atmosphere. Nitrogen circulation between abiotic environment and organism has five steps: nitrogen fixation, nitrification, assimilation, ammoniation and deacidification. Nitrogen fixation is the conversion of gaseous nitrogen to ammonia. This process is nitrogen fixed bacteria performed in soil and aquatic environments. These bacteria have discovered an enzyme called nitrogenase that breaks down nitrogen and binds it to hydrogen. Nitrogen-fixing bacteria must consume 12 grams of sugar to biologically immobilize monogram nitrogen. In the second stage, nitrification is the conversion of ammonia to nitrate. This is a two-step process carried out by soil bacteria

In the nitrogen cycle, bacteria convert nitrogen to ammonia in a process called nitrogen fixation. Bacteria also convert nitrogen to nitrate and nitrite. These forms of nitrogen can be consumed by primary producers to form nucleic acids and proteins. And consumers consume these nitrogen and make their own nitrogen compounds. Other bacteria get energy by converting nitric acid to nitrogen. And it is released to the atmosphere during the process called denitrification. Humans also add nitrogen to the biosphere by manufacturing and using fertilizers.
