Question

Assertion (A): Beggiatoa is not a chemoautotrophic bacterium. Reason (R): Chemoautotrophic bacteria derive carbon from CO\(_2\) and energy from oxidation of inorganic compounds.

• A. Both (A) and (R) are correct, and (R) is the correct explanation of (A).
• B. Both (A) and (R) are correct, but (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:

Chemoautotrophic bacteria use inorganic substances (e.g., sulfur, iron) to generate energy.

Answer 1

The Correct Option is D

Step 1: Understanding Beggiatoa's Metabolism
- Beggiatoa is a chemoautotrophic bacterium that derives energy from sulfur oxidation.
- Therefore, Assertion (A) is incorrect.
- Reason (R) is correct because chemoautotrophs derive energy from inorganic compounds.
