Answer:
Water molecules in general are carried to the shark by water currents. If there are no water currents then it is molecular diffusion, the random movement of molecules that disperses the odour away from the source. Diffusion is an extremely slow process as Vince experienced in his ink experiment.

diffusion can be defined as a phenomenon in which a substance moves from the region of higher concentration to the region of lower concentration system
Explanation:
- diffusion helps organism to get their nutrition and oxygen.
- In water the concentration of the oxygen is higher. When the Shark has lower amount of oxygen in the blood the oxygen diffuses from the water having higher concentration to the blood which has low concentration. This helps the Shark to survive in sea water.
