Question

Quizplus · Accepted Answer

The terms in the question are representing the processes involved in the nitrogen cycle. The sequence of terms in the first part of the question (NO₃^-) represents nitrification, which is the process of converting ammonium (NH4+) to nitrite (NO2-) and then to nitrate (NO3-), carried out by nitrifying bacteria. The sequence in the second part of the question (NO₂^--N₂O -N₂) represents denitrification, which is the process of converting nitrate (NO3-) to nitrogen gas (N2), carried out by denitrifying bacteria. The correct answer is therefore D, denitrification.
