Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Bacteria that survive in extreme environments belong to which kingdom?
A
Kingdom Fungi
B
Kingdom Protista
C
Kingdom Eubacteria
D
Kingdom Archaebacteria
Explanation: 

Detailed explanation-1: -Most extremophiles are microorganisms (and a high proportion of these are archaea), but this group also includes eukaryotes such as protists (e.g., algae, fungi and protozoa) and multicellular organisms. Archaea is the main group to thrive in extreme environments.

Detailed explanation-2: -Archaebacteria are known to be the oldest living organisms on earth. They belong to the kingdom Monera and are classified as bacteria because they resemble bacteria when observed under a microscope.

Detailed explanation-3: -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-4: -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-5: -Reason: Presence of peptidoglycan in cell wall help archaebacteria to survive in extreme conditions.
