Paramecium is part of the protist group, it is found in almost every water body.
They are unicellular organism, Their movement is thanks to the hair-like strutures called cilia. Thats the locomotive organs. they move at the same time against the water so they can create cinetic energy.
As other microorfanism, the Paramecium moves to sweep the prey, with the oral groove, and into the cell. It is feed by plants, like algae, small bits of animals and vegetables, also some bavteria and protozoa
