Problems faced by organisms that live in freshwater are without compensating mechanisms, their bodies tend to take in too much water.
Their bodies have a tendency to absorb too much water since freshwater organisms' environments are hypotonic in nature to their cells, which causes the organisms' bodies to do the same. They are unable to manage their tonicity. Only saltwater causes issues for the creatures who inhabit it.
The osmotic principle states that water travels from a location of low solute concentration (hypotonic) to a region of high solute concentration (hypertonic). As a result, the low solute content in the water creates difficulty for freshwater creatures since they have a tendency to use too much water.
