A) In the process X, protein is converted into ammonia by the action of bacteria while in the process Y nitrates present in the decaying remains get converted into free nitrogen gas.
B) In the process X, nitrates present in the soil get converted into free nitrogen gas while in the process Y, protein is converted into ammonia by the action of bacteria.
C) Process X represents the conversion of ammonia into nitrates while process Y represents the conversion of nitrates into the free nitrogen gas.
D) Process X represents the conversion of ammonia into nitrites while process Y represents the conversion of complex organic compound like proteins into ammonia.
Correct Answer: B
Solution :
In the given outline X and Y refer to denitrification and ammonification respectively.
