A fish swimming into an estuary from a river would have which of the following as its greatest physiological challenge?

#Unit 9. Diversity of Life Forms

  2. The low oxygen content would give the fish difficulty in swimming aerobically.
  3. The temperature change would stress the fish by denaturing its proteins.
  4. The change in water solute content would challenge the osmotic balance of the fish.
