Question

Will a fish replaced from a freshwater source to an aquarium with sea water be able
to survive? Give reasons.

Answer 1

Answer:

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.
