Freshwater protozoan require contractile vacuole to regulate the amount of water in its body /cell because the liquids ,in the form of waste water etc ,present in protozoan are more concentrated than the surrounding freshwater water due to presence of different acid ,etc . As a result concentration gradient develops which facilitate the flow of freshwater from surroundings inside the body of the protozoan . If this water keeps on filling inside the body then it may lead to damage to the metabolism of the protozoan & may also lead to the death of the organism .
Hence, a regulating body like contractile vacuole is needed to excrete out the extra water in the protozoan's body .

What dos the contractile vacuole do?
It eliminates excess water from the cytoplasm of freshwater protists.
Out of curiousity in science you did a lab involving freshwater organisms you wonder would a paramecium a protist die faster in saltwater or freshwater if its contractile vacuole stopped working?
nevermind my friend told me
How Parameciun could survive in freshwater which is hypotonic?
paramecium has an organelle called the contractile vacuole,since it is hypertonic water rushes in from its habitat but this vacuole excretes the water constantly so that the cell do not burst.
