Biologists have found a major supplier of nitrous oxide in the oceans

Archaea — unicellular organisms that make up about a third of the microbial "population" depths of the oceans, produce more nitric oxide, a potent greenhouse gas than the bacteria, which are considered his major "producers," according to the authors of an article published in the journal Science.

Archaea — single-celled organisms that differ from both the bacteria and all other organisms whose cells have a nucleus (eukaryotes). Many types of archaea are so-called extremophiles-organisms — they are found in hot springs on the ocean floor, at high pressure, extremely low temperatures, in acidic and alkaline environments, as
