it would die because they cant survive the freshwater trip
Water would diffuse into the cells of the jellyfish, causing it to bloat up and possibly burst.
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.
it would swell and finally burst apart.
It would lose salt into the water.
water leaves the cell causeing the cell to shrink.
Loss of water through osmosis is what would occur. The protozoan would shrivel up if it did not have a way to replace freshwater in its cells.
If a saltwater plant were placed in a freshwater aquarium, it would likely not survive due to the differences in salinity levels. Saltwater plants are adapted to living in environments with higher salt concentrations, and placing them in freshwater would disrupt their osmotic balance and lead to dehydration and eventual death.
Whatever the organism is it will die a dreadfully painfull death.
youd kill it

You'd probably get stung.
It depends. If you swallowed a Portuguese man of war, you would be dead.
