Quizplus · Accepted Answer

Only bacteria are known to have the enzyme nitrogenase, which breaks the strong triple bond of atmospheric nitrogen (N2) and converts it into a biologically usable form such as ammonia (NH3) or nitrate (NO3-). Plants, fungi, and protists do not have the enzyme nitrogenase and rely on bacteria to provide them with usable nitrogen.
