Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ are prokaryotes that live in extreme environments (ex:thermophiles and halophiles)
A
Archaea
B
Bacteria
C
Algae
D
Protozoa
Explanation: 

Detailed explanation-1: -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-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: -The term thermophiles are primarily used to refer to bacteria and archaea (thermophilic prokaryotes) that can thrive in habitats with high temperatures.

Detailed explanation-4: -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.
