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-).
Because of this catastrophic event the consequence will be Prolonged drought

-Engineering controls are practices which would lessen if not eliminate the exposure of a human being to chemical and other physical hazards by using or substitution of engineered machinery or tools.
-Engineering controls are methods that are built into the design of a plant, equipment or process to minimize the hazard. Engineering controls are a very reliable way to control worker exposures as long as the controls are designed, used and maintained properly. The basic types of engineering controls are:
process control, enclosure and/or isolation of emission source, ventilation.
