Assertion: Ammonia is converted into nitrate by soil bacteria like Nitrosomonas and Nitrobacter
Reason: Denitrification is carried by bacteria Pseudomonas and Azotobacter.

A

If both assertion 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
Ammonia is first oxidised to nitrite by the bacteria Nitrosomonas and/or Nitrosococuccus. The nitriate is further oxidised to nitrate with the help of the bacteria Nitrobacter, and/or Nitrocysits. These steps are called nitrification. These nitrifying bacteria are chemoautotrophs.
