The Nitrogen Cycle is close to the carbon cycle but slightly different for instance, 78% of our atmosphere is nitrogen and if less is becoming AIR and more carbon, then nitrogen fixation, the turning from useless nitrogen in the air into oxygen so we can actually use it.

Art:Nitrogen is fixed by the action of bacteria. It passes into the soil, into plant tissue, or into plant and then animal tissue. It returns to the atmosphere, and the cycle begins again.

The continuous sequence of events by which atmospheric nitrogen and nitrogenous compounds in the soil are converted, as by nitrification and nitrogen fixation, into substances that can be utilized by green plants, the substances returning to the air and soil as a result of the decay of the plants and denitrification.

Carbon cycle: Sources for CO2 in atmosphere: decay of vegetation; volcanic eruptions, exhalations of animals, burning of fossil fuels; Sinks for Carbon dioxide: biosphere (photosynthesis) and ocean uptake; CO2 is relatively well-mixed in the atmosphere
