Detailed explanation-1: -Typical environments from which pure cultures of archaeal species have been isolated include hot springs, hydrothermal vents, solfataras, salt lakes, soda lakes, sewage digesters, and the rumen.

Detailed explanation-2: -The archaebacteria are chemoautotrophs or chemosynthetic bacteria, and they are found in deep marine water where no light reaches them, unlike sulfur bacteria and methanogens.

Detailed explanation-3: -These deep-sea habitats host a group of extremophiles known as piezophiles, which survive and thrive under conditions of extremely high hydrostatic pressure [115, 116].

Detailed explanation-4: -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.
