Question

Fish takes in oxygen from the water. Can we say that fish takes in Oxygen
leaving hydrogen? Why/ why not?​

Answer 1

The oxygen that fish breathe is not the oxygen in H2O. Instead, the fish are breathing O2 (oxygen gas) that is dissolved in the water. ... Plus water is a lot heavier and thicker than air, so it takes a lot more work to move it around.
