The Nitrogen cycle

Things to know:

• The movement between the atmosphere, biosphere, and geosphere of nitrogen
• All organisms need nitrogen to survive and grow
• Since  nitrogen has such a strong bond, it is often in short supply
• This shortage of nitrogen leads to frequent limitation in plant growth

The Cycle:
1. Nitrogen fixation
2. Nitrogen Uptake
3. Nitrogen mineralization
4. Nitrificaiton
5. Denitrification 

There are a few dangers in humans playing with the nitrogen cycle. One very obvious way that the enviroment is being effected is the hole in the ozone, along with with an increase in temperature. Another major affect that can occur is the run off of the fertilizer off the plants and onto the ground. When we use that water is can cause cancer and respiratory distress in infants.   

Easy explination of the nitrogen cycle :)
