Question

The conversion of ammonia into nitrites and nitrates is called
A.Ammonification
B.Nitrification
C.Denitrification
D.All of the above

Answer 1

Hint: The process in which the ammonia is converted into nitrites and then further into nitrates is called Nitrification.

Complete answer: In the nitrogen cycle, the process in which the dead remains of plants and animals which are buried under soil and further decay and generate ammonia, carbon dioxide, and water with the support of fungi actinomycetes, this process in which the ammonia is formed is called as ammonification.
The further process of conversion of ammonia into nitrites and later into nitrates is called Nitrification, in this process, the ammonia is converted into nitrates by the action of Nitrosomonas bacteria which oxidizes the ammonia which is present in the soil and then converts into nitrites.
The nitrites are then converted into nitrates by the action of Nitrobacter species.
Some plants which do not absorb nitrates are converted as atmospheric nitrogen with the help of pseudomonas and clostridium, this process is known as Denitrification.

Hence, the correct option is ‘B’

Note: The nitrogen cycle is important as it is essential for the survival of the plants as they need nitrates to survive and grow, they make the soil rich and fertile.
