Detailed explanation-1: -Archaea is the main group to thrive in extreme environments. Although members of this group are generally less versatile than bacteria and eukaryotes, they are generally quite skilled in adapting to different extreme conditions, holding frequently extremophily records.

Detailed explanation-2: -Archaea that live in salty environments are known as halophiles. Archaea that live in extremely hot environments are called thermophiles. Archaea that produce methane are called methanogens. Archaea are known for living in extreme environments, but they also can be found in common environments, like soil.

Detailed explanation-3: -Extremophiles. Extremophiles are unicellular microbes (bacteria and archaea) that thrive in extreme environments.

Detailed explanation-4: -The Archaea are prokaryotes that inhabit extreme environments, such as inside of volcanoes, while Bacteria are more common organisms, such as E. coli.

Detailed explanation-5: -The domain Archaea corresponds to the kingdom Archaebacteria. Members of the domain Archaea are unicellular and prokaryotic, and they live in some extreme environments-in volcanic hot springs, brine pools, and black organic mud totally devoid of oxygen.
