1.	What is denitrification? Explain the process of denitrification.
Answer» Denitrification is the conversion, principally by bacteria, of compounds of nitrogen in solid and aquatic systems to the gases, nitrogen (N₂) and nitrous oxide (N₂O) and eventual release of these into the atmosphere. Denitrification occurs primarily in wet soils where water makes it difficult for microorganisms to get oxygen. Under these conditions, certain organisms – known as denitrifying bacteria – will process nitrate to gain oxygen, leaving free nitrogen gas as by-product.
