The step of the nitrogen cycle that is in red is called...

• Denitrification

• Nitrification

• Assimilation

• 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

Denitrification...

• 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

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

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