Global Implications of the Nitrogen Cycle

nitrogen cycle  Every living thing needs nitrogen This activity will teach students about how living things are able to get the nitrogen they need to survive  Certain types of bacteria are able to use the free nitrogen in the air to make nitrogen compounds through a process called nitrogen fixation

Step 1- Nitrogen Fixation- Special bacteria convert the nitrogen gas to ammonia which the plants can use ▫ Step 2- Nitrification- Nitrification In general, the N cycle processes of fixation, mineralization and nitrification increase plant available N Denitrification, volatilization, immobilization, and

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 Nitrogen exists in the atmosphere as N 2 ‍ gas In nitrogen fixation, bacteria convert N 2 ‍ into ammonia, a form of nitrogen usable by plants
