Question

Read the following statements regarding methanogens and select the correct option

i) They are included in the group Archaebacteria.
ii) They are responsible for the production of biogas in gobar gas plants.
iii) They live in hot sulphur springs.
iv) They are strictly anaerobic.

• A. Statements (i) and (ii) are correct
• B. Statements (i), (ii) and (iv) are correct
• C. Statements (ii), (iii) and (iv) are correct
• D. All statements are correct

Answer 1

Answer: (D)

All statements are correct

Methanogens are microorganisms that produce methane as a metabolic byproduct in anaerobic conditions. They are prokaryotic and belong to the domain called Archea. Methanogens play a vital ecological role in anaerobic environments. Methanogens are also found in hot springs, submarine hypothermal vents. Methogens are responsible for the production of biogas in gobar gas plants.

So, the correct answer is 'All statements are correct'.
