Question

The transformation of ammonia (NH3) into nitrate (NO3) is mostly performed by certain bacteria. This process is known as…

Answer 1

Answer:

b. Nitrification

Explanation:

Nitrifying bacteria are present in the soil that help in the oxidation process of ammonia that liberates the nitrite (NO2-) and nitrate (NO3-) compounds. These resulting compounds are captured by plants and this process is called nitrification. In the nitrification stage there are two chemical processes. That are:

• Nitrous: is the oxidation of ammonia (NH3) that results in the nitrite chemical compound (NO2-).

• Nitration: It is the oxidation of ammonia (NH3) that results in nitrate (NO3-).
