Fishes and bottom dwelling worms cope with the fluctuating salinity within estuaries over the tidal cycle with the use of transport system such as active and passive transport.
<h3>How active and passive transport system are used?</h3>
In salty water, fish and other marine organisms used active transport in which energy is used to remove salts from the body of these marine organisms because excess salts are harmful for them.
So we can conclude that Fishes use transport system such as active and passive transport to cope with the fluctuation of salt concentration.
