Will all the life in the ocean die if the ocean all the sudden lose its salinity?

Question

what kind of reaction or impact will it have on ocean life? i need source also im doing a research project

Answer 1

That is a thought provoker....

The short answer is no. Many bacteria and algae would survive and probably some species of fish, such as salmon and some sharks. Many species can tolerate a wide range of salinities, at least for a short time.

But for the most part, it would cause mass extinction since marine organisms have evolved to be in saline waters. They are physiologically adapted to retain water and excrete salts. If the salt was removed, their osmotic balance would be thrown off.

I don't think you are going to find a reference for this. the ocean is not going to become fresh. you may want to look for references on the physiology of marine organisms and relate how their osmotic function would fail. And find organisms that are anadromous or catadromous and discuss their possibility of survival.
