osmotonic environment

Answer 1

Saltwater fish are adapted to a hypertonic environment. In a hypertonic environment, the concentration of solutes (such as salt) outside the fish is higher than that inside its body, which poses challenges for maintaining osmotic balance. Saltwater fish have adaptations to excrete excess salt and retain water to survive in this environment.
