Answer: (C) Methanogens. Answer: (C) Methanogens Solution: Methanogens are archaebacteria present in the gut of ruminant animals like cows and buffaloes and are responsible for producing methane (biogas) from their dung.
- A.Halophiles
- B.Thermoacidophiles
- C.Methanogens✓
- D.Eubacteria
Correct Answer
(C) Methanogens
Solution & Explanation
Answer: (C) Methanogens Solution: Methanogens are archaebacteria present in the gut of ruminant animals like cows and buffaloes and are responsible for producing methane (biogas) from their dung. Halophiles live in extreme salty areas and thermoacidophiles in hot springs, so they are not linked to dung biogas; eubacteria are 'true bacteria', not the specific group named here.
