In sea water, the surrounding water is salty and hence is hypertonic to body cells. Thus, water will move from its higher concentration (in body) to its lower concentration (sea water) leading to exosmosis.Therefore, many fresh water animals can not live for long in sea water and vice varsa.

Explanation:
1. Hypertonic Environment: Seawater is hypertonic compared to the body cells of freshwater organisms. This means that the concentration of solutes in seawater is higher than the concentration of solutes in the cells of freshwater organisms.
2. Exosmosis: When freshwater organisms are placed in a hypertonic environment like seawater, they experience exosmosis. In exosmosis, water moves out of the cells of the organism into the surrounding seawater in an attempt to equalize the concentration of solutes on both sides of the cell membrane.
3. Effects of Exosmosis: As water moves out of the cells, the cells shrink and lose turgor pressure. This can lead to dehydration and ultimately cell death. The loss of water from the cells also disrupts cellular functions and can lead to organ failure and death of the organism.
4. Inability to Survive: Due to the harmful effects of exosmosis in a hypertonic environment like seawater, many freshwater organisms cannot survive for long periods in such conditions. They are adapted to living in environments with lower solute concentrations, and their cells are not equipped to handle the osmotic stress imposed by seawater.
In conclusion, the hypertonic nature of seawater compared to the body cells of freshwater organisms leads to exosmosis, which can be detrimental to the health and survival of these organisms. This explains why many freshwater organisms cannot live for long in seawater.
