The Nitrogen Cycle
By: Gabi Conners
Nitrification - ammonium changes into nitrates and gets absorbed by plants.
Denitrification - nitrogen in the soil goes back into the atmosphere.
Ammonification - the decaying process; when an organism dies, decomposers (fungi, bacteria, etc.) turn nitrogen back into ammonium; reenters the nitrogen cycle.
*All processes are carried out by the use of special bacteria!
