The step of the nitrogen cycle that is in red is called...
Denitrification
Nitrification
Nitrogen Fixation
Ammonification
Nitrogen fixation...
animals eat the plants and other animals that contain nitrogen and release it through their waste
Bacteria in the soil and lightning in the atmosphere “fix” the nitrogen
Once in the ground, bacteria in the soil also nitrify the nitrogen
plants absorb nitrogen through their roots and return it back to the atmosphere
