Question

definition of denitrification class 8th​

Answer 1

Answer:

Denitrification is defined as the “microbial reduction of nitrate or nitrite coupled to electron transport phosphorylation resulting in gaseous N either as molecular N2 or as an oxide of N.” The key to denitrification as defined is the availability of the N oxides, nitrite (NO2−) or nitrate (NO3−), which are formed from the autotrophic nitrification pathway substrate, ammonia (NH3), which is derived from ammonium (NH4+).

OR

the loss or removal of nitrogen or nitrogen compounds

Answer 2

Explanation:

Denitrification is a microbially facilitated process where nitrate is reduced and ultimately produces molecular nitrogen through a series of intermediate gaseous nitrogen oxide products.
