Question

Fish species that live in fresh water have to remove excess
water as waste from their bodies. Fish species that live in
salt water have bodies that keep in as much water as
possible. Using what you know about osmosis, explain
these observations.

Answer 1

Answer: Organisms that live in a hypotonic environment such as freshwater, need a way to prevent their cells from taking in too much water by osmosis. Freshwater and saltwater fish have the ability to adjust to the osmotic pressure in the water around them.
