Question

Assertion (A): Nitrosomonas is a Chemoautotrophic bacteria.
Reason (R): Chemoautotrophs derive energy from sunlight and carbon from CO\(_2\).

• A. A and R are Correct and R is the Correct explanation of A
• B. A and R are Correct and R is not the Correct explanation of A
• C. A is Correct but R is incorrect
• D. A is incorrect but R is correct

Hint:

It's important to distinguish between different types of autotrophs: chemoautotrophs and photoautotrophs, based on their energy sources.

Answer 1

The Correct Option is C

Evaluating the assertion and reason.
Nitrosomonas is indeed a chemoautotrophic bacteria, using chemical energy to fix CO₂. However, the reason is incorrect because chemoautotrophs derive energy from chemical reactions, not from sunlight; photoautotrophs use sunlight.
