Detailed explanation-1: -Paramecium is a single-celled protozoan. It obtains its food in the following manner: The hair-like structures called cilia present on the paramecium help in collecting the food and movement. They sweep the food inside the paramecium through the oral groove.

Detailed explanation-2: -To gather its food, the paramecium uses its cilia to sweep the food along with some water into the cell mouth after it falls into the oral groove. The food goes through the cell mouth into the gullet, which is like the stomach.

Detailed explanation-3: -Gullet in a paramecium acts as buccal cavity where the food is converted into food vacuoles for digestion.

Detailed explanation-4: -Gathering food To gather food, the Paramecium makes movements with cilia to sweep prey organisms, along with some water, through the oral groove (vestibulum, or vestibule), and into the cell. The food passes from the cilia-lined oral groove into a narrower structure known as the buccal cavity (gullet).

Detailed explanation-5: -They eat other microorganisms like bacteria or algae by sweeping them towards their cell mouths (cytostomes) where they’re absorbed and digested. These cilia, however, are useful for more than just eating. Cilia are able to move in a coordinated way to propel a Paramecium forward.
