A) Both processes move nitrogen from land to oceans.
B) Both processes release nitrogen into the atmosphere.
C) Both processes remove nitrogen from the atmosphere.
D) Denitrification takes nitrogen from the air and makes it usable by plants;nitrogen fixation reverses this process.

Question

Quizplus · Accepted Answer

Nitrogen fixation is the process of converting atmospheric nitrogen gas (N2) into a form that plants can use, while denitrification is the process of converting nitrogen in the soil back into atmospheric nitrogen gas. Thus, nitrogen fixation takes nitrogen from the air and makes it usable by plants, while denitrification reverses this process.
