The Nitrogen Cycle
... Description of the Nitrogen Cycle • N2 gas in the atmosphere must be taken in by symbiotic bacteria in the roots of plants (legumes) through nitrogen fixation. Then other bacteria change the nitrogen so it can be taken up by plants. Animals eat plants and get nitrogen. When plants and animals die, ...
