C) Assimilation
D) Nitrogen fixation
E) Nitrification

Question

Quizplus · Accepted Answer

Assimilation is the step in the nitrogen cycle where plants and animals incorporate the NO3- and ammonia formed through fixation, nitrification, and ammonification into organic molecules such as DNA, amino acids, and proteins. Most bacteria are involved in the other steps (ammonification, denitrification, nitrogen fixation, and nitrification) but do not perform assimilation in the same way plants and animals do.
