Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Methanogens are anaerobic archaebacteria that inhabit marshy places, sewage treatment plants, and the rumen of cattle.
They decompose cellulose-containing materials and release gases during metabolism.
Step 1: Understand the habitat of methanogens.
Methanogens are commonly found in:
• Swamps
• Marshes
• Sewage digesters
• Rumen of cattle These environments are oxygen deficient.
Step 2: Study their metabolism.
Methanogens break down organic matter anaerobically. During this process they generate: \[ \text{Methane} \] along with \[ CO_2 \] and \[ H_2 \]
Step 3: Apply NCERT information.
The gas mixture produced during methanogenic activity contains: \[ CH_4,\ CO_2,\ H_2 \]
Step 4: Select the correct answer.
Hence, \[ \boxed{\text{Methane, CO}_2 \text{ and Hydrogen}} \]
