The Total solution for NCERT class 6-12
The chances of survival of marine fish will reduce if placed in a fresh water aquarium as their bodies are altered to higher salt concentrations as provided by marine environments. In a fresh water environment, fishes fail to regulate the water which enters the body through the process of osmosis. Due to the presence of a hypotonic environment outside the fish’s body, water enters their body which causes their body to swell leading to the death of the marine fish.
