How does Paramecium ingest food?
By moving cilia toward a specific spot
Paramecium is a ciliated unicellular protozoan. Its whole surface is covered with tiny hair-like cilia that beat in a coordinated way. Along one side there is a shallow depression called the oral groove, at the base of which lies the cytostome (cell mouth).
To feed, Paramecium sweeps water containing food particles into the oral groove by moving its cilia toward that specific spot. The food particles are then packaged into a food vacuole at the cytostome and digested inside the cell. It does not use pseudopodia (that is Amoeba), it does not simply absorb food across the general surface, and it does not change its whole body shape while feeding.
Hence, the answer is By moving cilia toward a specific spot.
