Summary Introduction

To determine: How the organism is able to survive in the changing salt concentrations in estuaries.

Concept introduction:

Osmosis is the process in which the water molecules move from a region of low solute concentration to that of high solute concentration, to maintain osmoregularity. Many aquatic organisms that thrive in different concentrations of salts, such as in estuaries regulate their internal salt concentration with that of the external salt concentration.
