Question

Quizplus · Accepted Answer

Nitrogen fixation involves the conversion of atmospheric nitrogen gas (N2) into ammonia (NH3) or ammonium ions (NH4+) by certain species of bacteria and archaea. This process is essential for the creation of biologically usable forms of nitrogen for plant growth and other biological processes. Option A refers to nitrification, which is the process of converting ammonium ions to nitrate (NO3-). Option B refers to ammonification, which is the process of decomposing organic nitrogen compounds and releasing ammonium ions. Option D is incorrect because nitrogen fixation specifically refers to the conversion of N2 to ammonia or ammonium, not nitrate.
