All archaea and bacteria are microbial species (living things too small to see with the … eye) and represent a vast number of different evolutionary lineages. In eukarya, you'll find animals, plants, fungi and some other organisms called protists.

Some archaea are mesophiles, and many are extremophiles, preferring extreme hot or cold, extreme salinity, or other conditions that are hostile to most other forms of life on earth. Their metabolism is adapted to the harsh environments.

Humans appear to have low levels of archaea, and so far they have been found in the human gut (part of digestion and metabolism), on the skin, and in subgingival dental plaque (and perhaps involved with periodontal disease).

So far, most archaea are known to be beneficial rather than harmful to human health. They may be important for reducing skin pH or keeping it at low levels, and lower pH is associated with lower susceptibility to infections.

B12 is synthesized by only certain bacteria and archaeon, but not by plants or animals. The synthesized B12 is transferred and accumulated in animal tissues, even in certain plant tissues via microbial interaction.
