Detailed explanation-1: -Methanogenesis is an anaerobic respiration that generates methane as the final product of metabolism. In aerobic respiration, organic matter such as glucose is oxidized to CO2, and O2 is reduced to H2O. In contrast, during hydrogenotrophic methanogenesis, H2 is oxidized to H+, and CO2 is reduced to CH4.

Detailed explanation-2: -Methanogenic archaea, or methanogens, are an important group of microoraganisms that produce methane as a metabolic byproduct under anaerobic conditions. Methanogens belong to the domain archaea, which is distinct from bacteria.

Detailed explanation-3: -Methane may also be produced under aerobic conditions in near-surface ocean water, a process which likely involves the degradation of methylphosphonate.
