Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A halophile would grow best in
A
acid pools.
B
freshwater ponds.
C
hot geyser springs.
D
salt lakes.
Explanation: 

Detailed explanation-1: -Halophiles can be found in water bodies with salt concentration more than five times greater than that of the ocean, such as the Great Salt Lake in Utah, Owens Lake in California, the Urmia Lake in Iran, the Dead Sea, and in evaporation ponds.

Detailed explanation-2: -Halophilic extremophiles, or simply halophiles, are a group of microorganisms that can grow and often thrive in areas of high salt (NaCl) concentration.

Detailed explanation-3: -A halophile is an organism that lives in an environment that has a high salinity such as ocean and solid salt crystals. Halophiles are found thriving in habitats with a high concentration of salt, such as in the Great Salt Lake in Utah and Owens Lake in California.

Detailed explanation-4: -Halophilic archaea dominate the Earth’s many hypersaline environments such as salt lakes, underground salt deposits, and solar salterns [1, 2, 3, 4, 5]. These microorganisms live at low water activity and can tolerate sodium chloride brine at saturation, even in fluid inclusions of salt (halite) crystals [6].
