Which organisms require high salt concentration in the medium?

Explanation:
Organisms that require high salt concentration for growth are halophiles. Their cellular systems are adapted to saline environments, and salt is essential for maintaining osmotic balance and many essential enzyme activities. You’ll find them in places with high salinity, like salt lakes or salt pans, where most other organisms can’t survive. By contrast, thermophiles thrive at high temperatures, acidophiles at low pH, and alkaliphiles at high pH; these groups are defined by temperature or pH rather than salt needs, so they don’t specifically require a high-salt environment for growth.
