Question

If a marine fish is placed in a fresh water aquarium, will the fish be able to survive? Why or why not?

Answer 1

If a marine fish is placed in a freshwater aquarium, fish would not be able to survive because fishes are adapted to sea water, fishes body are hypertonic but when water moves to an aquarium it becomes hypotonic. They are unable to regulate the metabolic process in the changed environment and they die.
