NEET BIOLOGY

Detailed explanation-1: -Methanogens belong to archaebacteria. They are strict anaerobes . They are autotrophs which obtain both energy and carbon from decomposition products. They occur in marshy areas where they convert formic acid and carbon dioxide into methane with the help of hydrogen.

Detailed explanation-2: -Methanogens are archaea bacteria that produce methane as a metabolic by-product. Examples of methane-producing genera are Methanobacterium, Methanosarcina, Methanococcus, and Methanospirillum.

Detailed explanation-3: -Methanogens are anaerobic archaea that grow by producing methane gas. These microbes and their exotic metabolism have inspired decades of microbial physiology research that continues to push the boundary of what we know about how microbes conserve energy to grow.

Detailed explanation-4: -Methanogens belong to Archaebacteria.

Detailed explanation-5: -Methanogenic archaea are the only known microorganisms that produce methane, and these microbes can inhabit extreme conditions in the environment. Methanogens in agricultural activities, including livestock, rice farming and manure, contribute a significant amount of methane.
