Final answer:
Halophiles are organisms that require high salt concentrations in their environment for growth and survival.
Step-by-step explanation:
Halophiles are organisms that require high salt concentrations in their environment for growth and survival.
These organisms, such as Halobacterium, can tolerate salt concentrations that exceed the tolerance levels of most other organisms and can even survive in saturated brine solutions.
They are considered extremophiles and are adapted to live in environments with high salinity, such as the Dead Sea and some salty lakes.
