Correct Answer: Conversion of ammonia to nitrites


Solution : The correct option is Conversion of ammonia to nitrites.

Nitrification is the process by which some bacteria in the soil convert ammonia (NH3) and ammonium ions (NH4+) to nitrite (NO2-) and ultimately to nitrate (NO3-). It is an important phase in the nitrogen cycle that contributes significantly to the availability of nitrogen to plants for growth. Nitrification is caused by two kinds of bacteria: Ammonia-Oxidizing Bacteria (AOB): AOB converts ammonia (NH3) to nitrite (NO2-). NOB: Nitrite-Oxidizing Bacteria (NOB) convert nitrite (NO2-) to nitrate (NO3-).
