EVERYDAY SCIENCE

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 are famous for their love of living in extreme environments. If it’s super hot (more than 100° Celsius), freezing, acidic, alkaline, salty, deep in the ocean, even bombarded by gamma or UV radiation, there’s probably life there, and that life is probably archaeal species.

Detailed explanation-3: -Reason: Presence of peptidoglycan in cell wall help archaebacteria to survive in extreme conditions.

Detailed explanation-4: -Many species of Archaebacteria are extremophiles and live in extreme environments, whereas Eubacteria are found in all environments.

Detailed explanation-5: -They live in the anoxic muds of marshes and at the bottom of the ocean, and even thrive in petroleum deposits deep underground. Some archaeans can survive the dessicating effects of extremely saline waters. One salt-loving group of archaea includes Halobacterium, a well-studied archaean.
