Detailed explanation-1: -Archaea is the main group to thrive in extreme environments .
Detailed explanation-2: -Presence of peptidoglycan in cell wall help archaebacteria to survive in extreme conditions.
Detailed explanation-3: -Hyperthermophilic (ie, high-temperature-loving) archaebacteria, found in submarine hydrothermal areas (see Stetter, 1982; Segerer, et al., 1985; Stetter, 1986; Huber et al., 1989; Neuner et al., 1990), thrive at temperatures in the range 80-110°C, and they are unable to grow below 60°C.
Detailed explanation-4: -Archaebacteria are special since they live in some of the most harsh habitats such as extreme salty areas (halophiles), hot springs (thermoacidphiles) and marshy bacteria in having a different cell wall structure and this feature is responsible for their survival in extreme conditions.
