Microbial degradation of nitrates into atmosphericnitrogen is known as:

Ammonification
Nitrification
Denitrification
Putrefaction

Solution:

Denitrification is the biological conversion of nitrate to nitrogen gas, nitric oxide or nitrous oxide. It refers to nitrate reduction by bacterial species such as Pseudomonas and Clostridium , usually in anaerobic conditions that ultimately produces molecular nitrogen

(N_2)

. These bacteria use nitrate as an electron acceptor instead of oxygen during respiration.
