Nitrogen Cycling in the Open Ocean · Nitrogen gas from the atmosphere dissolves into seawater at the ocean surface · Dissolved nitrogen gas is taken up by

The global nitrogen cycle is central to the biogeochemistry of the Earth, with large natural flows of nitrogen from the atmosphere into All of the nitrogen that is fixed out of the atmosphere goes into plants and then possibly into animals and then as those animals and plants die
