Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What type of organism can be found in extreme environments such as hot springs?
A
viruses
B
archaea
C
eukaryotes
D
None of these
Explanation: 

Detailed explanation-1: -"Extremophiles” are organisms with the ability to thrive in extreme environments such as hydrothermal vents .

Detailed explanation-2: -Whenever you see a hot, muddy, acidic spring, you are probably seeing the results of a thriving community of archaeal cells called Sulfolobus. This is the archaea most often isolated and most well known by scientists.

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 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.
