Detailed explanation-2: -food vacuole – a cavity within the amoeba in which food is digested (broken down in order to be absorbed by the amoeba).

Detailed explanation-3: -The food vacuole or digestive vacuole is a membrane-bound cell organelle associated with a digestive function. They possess the digestive enzymes that help with the breaking down of nutrients. They take up the food material by the process of phagocytosis and the ingested food is digested by this vacuole.

Detailed explanation-4: -A food vacuole is basically a storage unit of food for the amoeba. It is formed only when the amoeba has engulfed its prey completely, following which digestive enzymes are released into the vacuole for digestion. Then, the food is absorbed and the waste is excreted.
