When a marine water protozoan is placed in fresh water, it experiences osmotic stress due to the difference in solute concentration. Freshwater has a lower concentration of solutes compared to the protozoan's internal environment, leading to water entering the cell through osmosis. This can cause the protozoan to swell and potentially burst, as they are not adapted to cope with such a drastic change in osmotic pressure. To survive, they would need to actively regulate their internal conditions or find a way to return to a saltier environment.
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
Ascarids (round worms) are generally parasitic (so not really marine or fresh water) and worms are either male or female.
Fish are a part of the marine biome. There are two forms of marine biomes: fresh water biomes and salt water biomes.
Platypuses are not marine vertebrates. They can only live near fresh water.
Usually freshwater
no they are marine only
Not necessarily. It can be fresh, brackish, or marine.
