Question

Quizplus · Accepted Answer

Nitrogen is made available to plants through the processes of ammonification (conversion of organic nitrogen to ammonia), nitrification (conversion of ammonia to nitrate by bacteria), and nitrogen fixation (conversion of atmospheric nitrogen to a form plants can use, such as ammonia). These processes collectively contribute to the nitrogen cycle, making nitrogen accessible to plants in a form they can absorb and use.
