If a jellyfish was placed in a freshwater lake, the jellyfish would be placed in a hypotonic environment. Osmosis says that water moves from areas of low solute concentration to high concentration, in order to reach a dynamic equilibrium. In other words, due to the fact that the jellyfish was placed in a hypotonic environment, or an area of low solute concentration compared to the jelly fish, its cells would be flooded with the fresh water and its cells would burst, causing the death of the jellyfish.
