Solution

Cilia are hair-like bristles on a Paramecium used in locomotion and to find food. An oral groove is a mouth for a Paramecium, and food vacuoles store food in the cell body of the Paramecium. All of these are cell organelles used to ingest, digest, and egest preformed food, which is heterotrophic nutritrion. An autotroph can make its own food using chloroplasts
