Why does the paramecium live in water scientifically speaking?

Paramecium live in water primarily because they are protists that require a moist environment to survive and carry out essential biological functions. The aquatic habitat provides the necessary medium for nutrient absorption, locomotion, and waste removal through osmosis. Additionally, the water serves as a habitat rich in bacteria and other microorganisms, which are crucial food sources for paramecium. Their cilia, which facilitate movement and feeding, are also adapted for life in an aquatic environment.
