Archaea use more diverse energy sources than eukaryotes, ranging from organic compounds such as sugars, to ammonia, metal ions or even hydrogen gas. The salt-tolerant Haloarchaea use sunlight as an energy source, and other species of archaea fix carbon (autotrophy), but unlike cyanobacteria , no known species of archaea does both.

Euryarchaeota (from Ancient Greek εὐρύς eurús, "broad, wide") is a kingdom of archaea. [3] Euryarchaeota are highly diverse and include methanogens, which produce methane and are often found in intestines; halobacteria, which survive extreme concentrations of salt; and some extremely thermophilic aerobes and anaerobes, which generally live at temperatures between 41 and 122 °C.

Haloarchaea (halophilic archaea, halophilic archaebacteria, halobacteria) [1] are a class of prokaryotic archaea under the phylum Euryarchaeota, [2] found in water saturated or nearly saturated with salt. 'Halobacteria' are now recognized as archaea rather than bacteria and are one of the largest groups or archaea.
The tree of life. Two domains of life are Bacteria (top branches) and Archaea (bottom branches, including eukaryotes). The two-domain system is a biological classification by which all organisms in the tree of life are classified into two domains, Bacteria and Archaea.
Thermophiles produce some of the bright colors of Grand Prismatic Spring, Yellowstone National Park. A thermophile is an organism—a type of extremophile—that thrives at relatively high temperatures, between 41 and 122 °C (106 and 252 °F).
In 1985, Shimizu Construction developed a bioreactor that uses Methanosarcina to treat waste water from food processing plants and paper mills. The water is fed into the reactor where the microbes break down the waste particulate. The methane produced by the archaea is then used to power the reactor, making it cheap to run.
