The mode of nutrition in amoeba is holozoic. Amoeba digests the food inside food vacuole that contain enzyme for digestion.

In amoeba, digestion of food takes place inside the food vacuole. The food vacuole is a small space within the cytoplasm of the amoeba where food is engulfed and broken down.
1. Food ingestion: Amoebas are unicellular organisms that obtain their food by surrounding and engulfing it with their pseudopodia, which are temporary extensions of their cell membrane. When an amoeba comes in contact with a food particle, it extends its pseudopodia around the food and forms a food vacuole.
2. Enzyme secretion: Once the food is enclosed in the food vacuole, the amoeba secretes digestive enzymes into the vacuole. These enzymes help to break down the complex molecules of the food into simpler substances that can be easily absorbed by the amoeba.
3. Intracellular digestion: Inside the food vacuole, the digestive enzymes act on the food particles and break them down into smaller molecules such as glucose, amino acids, and fatty acids. This process is known as intracellular digestion since it occurs within the cell.
4. Absorption: After the food is broken down into smaller molecules, these molecules are absorbed into the cytoplasm of the amoeba. The nutrients are then utilized by the amoeba for energy, growth, and other metabolic processes.
5. Egestion: Any undigested or unabsorbed waste material is expelled from the amoeba through a process called exocytosis. The food vacuole fuses with the cell membrane, and the waste material is released outside the cell.
The food vacuole acts as a digestive chamber within the amoeba, allowing it to break down and absorb nutrients from its food. This process is essential for the amoeba's survival and provides it with the necessary energy and nutrients to carry out its life processes.
