Question

mention 3 points of difference between nitrification and denitrification

Answer 1

INTRODUCTION:Nitrification and denitrification are the two major stages in nitrogen cycle

The differences between nitrification and denitrification are as follows

1)Conversion of free nitrogen present in the atmosphere into compounds of nitrogen is Called nitrification. Nitrogen makes its way back into the atmosphere through a process called denitrification.2)Nitrogen fixing bacteria are Nitrosomonas , nitrobacters etc(in nitrification)
Bacteria responsible for this are thiobacillus,paracoccus etc(in denitrifrication)
3)Atmospheric Nitrogen (N2)converted to nitrates(NO3) or ammonia(nitrification) Nitrates(NO3) are converted to gaseous nitrogen(N2)(denitrification)

Answer 2

Nitrification is the biological process of oxidation of ammonia or ammonium compound to nitrite, subsequently followed by the oxidation of nitrite to nitrate.
Denitrification, on the other hand, is a biological process of nitrate reduction, which may ultimately produce molecular nitrogen. This is the primary difference between the two processes.
The former is an aerobic process performed by small groups of autotrophic bacteria and archaea. The latter process is performed by a large group of heterotrophic facultative anaerobic bacteria.
While nitrification is an intermediate step in the nitrogen cycle, denitrification is the final step by which nitrogen is released back into the atmosphere.
