Answer:
Ciliates are required for a paramecium to survive in its environment
Step-by-step explanation:
The protists that are of single-cell is known as paramecium, especially found in the aquatic animal. They are long, shaped like slipper and body covered with cilia. They belong to the organelle group of Ciliates as their body has cilia covering it. This helps in their body movement in their environment of aqua.
