Assertion: Nitrate present in the soil is reduced to nitrogen by the process of denitrification
Reason: Denitrification is carried by bacteria Pseudomonas asnd Azotobacter.

A

If both assertio and reason are true and reason is the correct explanation of assertion

B

if both assertion and reason are true but reason is not the correct explanation of assertion

C

if assertion is true but reason is false

D

if both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
C
The nitrate formed by nitrification is absorbed by plants and is transported to the leaves. In leaves, it is reduced to form ammonia that finally forms the amine group of amino acids. Nitrate present in the soil is also reduce to nitrogen by the process of denitrication. Denitrification is carried by bacteria Pseudomonas and Thiobacilus.
