Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
extreme environments, like the vent floors of the ocean
A
bacteria
B
virus
C
archaea
D
algae
Explanation: 

Detailed explanation-1: -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-2: -Organisms that live around hydrothermal vents don’t rely on sunlight and photosynthesis. Instead, bacteria and archaea use a process called chemosynthesis to convert minerals and other chemicals in the water into energy.

Detailed explanation-3: -Typical environments from which pure cultures of archaeal species have been isolated include hot springs, hydrothermal vents, solfataras, salt lakes, soda lakes, sewage digesters, and the rumen.

Detailed explanation-4: -Archaea are microorganisms that define the limits of life on Earth. They were originally discovered and described in extreme environments, such as hydrothermal vents and terrestrial hot springs. They were also found in a diverse range of highly saline, acidic, and anaerobic environments.
