Hint: Methanogens are the microorganisms that produce methane in their metabolic reactions.
Complete Answer:
- Methanogens are the prokaryotic bacteria and they belong to Archaea.
- Prokaryotes are those organisms that lack a well defined nucleus and membrane bound cell organelles.
- These microorganisms produce methane as a metabolic byproduct in hypoxic conditions.
- Production of methane is called methanogenesis.Methane is a potent greenhouse gas.
- The shape of methanogens can be spherical (cocci) or rod shape (bacilli).There are over 50 described species of methanogens.
- Methanogens are anaerobic microorganisms , they cannot work in aerobic conditions. These bacteria are too sensitive for the presence of Oxygen.
- Methanogens are found in the guts of animals, deep layers of marine sediments, in wetlands, etc.
- In addition to methane, methanogens also produce carbon dioxide and hydrogen sulphide.
Hence, option A is the correct answer for this question.
Note: Methanogens play a vital ecological role by removing excess Hydrogen and fermentation products by anaerobic respiration. They also [lay a key role in remineralization of organic carbon.
