Quizplus · Accepted Answer

The nitrogen cycle consists of five main steps: nitrogen fixation (conversion of atmospheric nitrogen into a usable form for plants), nitrification (conversion of ammonia to nitrate by bacteria), assimilation (uptake of nitrates by plants), ammonification (conversion of organic nitrogen back into ammonia by decomposers), and denitrification (conversion of nitrate back into nitrogen gas by bacteria), making option C correct.
