How does the nitrogen cycle work? ▫. Step 1- Nitrogen Fixation- Special bacteria
convert the nitrogen gas (N2 ) to ammonia (NH3) which the plants can use. ▫.
The steps of the nitrogen cycle are nitrogen fixation, nitrification, ammonifcation
and denitrification. During the first step, nitrogen fixation, special bacteria convert
