Amoeba follows holozoic mode of nutrition in which the solid food particles are ingested which are then acted upon by enzymes and digested.

Steps of Nutrition in Amoeba:

• Amoeba engulfs food by temporary finger-like projections of its body surface called pseudopodia.
• When a pseudopodium fuses with the food particle, it forms a food vacuole.
• Complex substances are broken down into simple substances inside the food vacuole. These simple substances are then diffused into the cytoplasm.
• The remaining unwanted material is taken to the cell surface and is thrown out.
