When a marine protozoan is transferred to a fresh water medium, it may experience osmotic stress due to differences in salt concentrations. This can disrupt its internal balance of water and salts, leading to potential cell damage or death. Additionally, the change in environment could impact its ability to obtain nutrients and interact with other organisms that are specific to marine habitats.
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.
marine fish lay eggs in fresh water river
no
the marine fish would pretty much suffocate and die. so putting marine fish in fresh water is not a good idea.
Fresh water- Rivers Marine water-Oceans Brackish water-Lagoons
