The transformation of ammonia (nh3) into nitrate (no3) is mostly performed by certain bacteria. this process is known as…
a. denitrification
b. nitrification
c. ammonification
d. nitrogen fixation
e. nitrogen assimilation

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-).
