Answer:
Nitrification is an aerobic process performed by nitrifying bacteria or archaea which transform ammonia into nitrite (NO2-) and then the nitrite to nitrate (NO3−). Nitrates are inorganic forms of nitrogen that plants can use as a nitrogen source so, the nitrification is an important step in the nitrogen cycle in soil.
(NH4+ → NO2− → NO3−)
