Nitrogen fixation...

Back

Bacteria in the soil and lightning in the atmosphere “fix” the nitrogen

Front

Nitrification...

Back

Once in the ground, bacteria in the soil also nitrify the nitrogen

Front

Ammonification...

Back

animals eat the plants and other animals that contain nitrogen and release it through their waste

Front

Assimilation...

Back

plants absorb nitrogen through their roots and return it back to the atmosphere

Front

Denitrification...

Back

nitrogen is released back into the atmosphere from the animal’s waste or decomposers
