Document Summary
The nitrogen (n2) cycle explains the conversion of n2 in its gas form to a form that the carbon (co2) cycle is the movement and circulation of carbon throughout all living. How do humans impact it? and nonliving environments. This circulation occurs through photosynthesis, cellular respiration, and the process of burning fossil fuel. Humans have increased the amount of co2 in our atmosphere through mostly through excessive usage of fossil fuels, and effectively trapping magnitudes of co2 that will raise our global temperature. What is nitrogen fixation and why is this very important? organisms can actually use. This cycle takes five steps: nitrogen fixation, nitrification, assimilation, ammonification, and denitrification. Humans have managed to double nitrogen fixation through increased production in corporate fertilizers and, of course, fossil fuel burning. How do humans impact it? atmosphere, land, and oceans. Water moves through precipitation (rain and snow), evaporation, and transpiration (loss of water vapor from land plants).
