Nitrogen Cycle

Hi! My name is Adam. I'm a nitrogen atom. I go through the nitrogen cycle! Come with me and i'll show you what it's all about!
First we start in the atmosphere. Our goal right now is to get fixed by lightning or bacteria. Some of my lucky friends got stuck by lightning and got fixed!
Yea!
Woo-hoo!
Now, I just turned into a just turned into Nitrogen gas, or N2! I can now go into a plant as food, or I can continue through the cycle. I plan to continue the cycle, but only time will tell.
Yes! I continued through the cycle! I just went through ammonification. A bacteria turned me into ammonium ions, or NH4. On to the next step!
Now I'm in the process of Nitrification. This is a 2-step process. First a bacteria turns me into a nitrite ions, or NO2, which I am now. Then I turn into nitrate ions, or NO3, Which I'm about to be. Lets go to the last step!
Now I'm in a process called denitrification. In this process, I get turned back into Nitrogen gas, or at least an atom of it. I'm already floating up! Weeeeee!
