Nitrogen cycle Nitrogen gas is a colourless‚ odourless and non-toxic gas which makes up about 78 percent of the atmosphere. Nitrogen is extremely important to living material; in fact plants‚ animals and humans could not live without it. Sprent (1987) argued that nitrogen cycle is the most important process to living organisms after the carbon cycle. But nitrogen exists as dinitrogen (N2) in the atmosphere‚ which living things‚ particularly plants‚ cannot synthesize (citation) The process of nitrogen

------------------------------------------------- The Processes of the nitrogen cycle Nitrogen fixation Atmospheric nitrogen must be processed‚ or "fixed" (see page on nitrogen fixation)‚ in order to be used by plants. Some fixation occurs in lightning strikes‚ but most fixation is done by free-living or symbiotic bacteria. These bacteria have the nitrogenase enzyme that combines gaseous nitrogen with hydrogen to produce ammonia‚ which is then further converted by the bacteria to make their own organic

I will start by describing the carbon cycle and how elements of my lifestyle impact the cycle. Photosynthesis converts the Carbon dioxide gas that exists in the atmosphere and in dissolved water to organic carbon. Organic carbon is brought back into carbon dioxide gas by a process called respiration. There are sources of organic carbon underground in the form of fossil fuels‚ human emissions and volcanic activity brings the stored carbon back into the cycle. As a human being who feed‚ move‚ breath
