Do Methanogenic Archaeans Release Methane In Carbon Cycle?

Do Methanogenic Archaeans Release Methane In Carbon Cycle? Methanogens carry out methanogenesis which produces methane (CH4), a potent greenhouse gas. Do archaea produce methane from carbon dioxide? Methane is an end product of anaerobic degradation of organic compounds in fresh water environments such as lake sediments and the intestinal tract of animals. Methanogenic archaea produce
