Vedclass · Answer

(B) $Methanogens$ are a group of $Archaebacteria$ that produce methane gas as a metabolic byproduct in anoxic conditions.They are obligate anaerobes,meaning they cannot survive in the presence of oxygen.They are commonly found in oxygen-deficient environments such as marshes,swamps,waterlogged paddy fields,and the rumen (a part of the stomach) of ruminant animals like cattle.In the rumen,they help in the breakdown of cellulose.Because they are present in the gut of cattle,their excreta (dung) is rich in these bacteria,making a cattle yard a highly abundant source of $Methanogens$.They are also used in biogas (gobar gas) plants to produce methane from animal waste.
