Detailed explanation-1: -Amoeba does not have a fixed limb or any part for helping it to ingest the food. It ingests food by the process of phagocytosis. It develops pseudopodia, temporary projections, to take the food inside its body. Pseudopodia literally means false feet.
Detailed explanation-2: -Nutrition in an Amoeba occurs through a process called phagocytosis. Phagocytosis is the process by which the food is engulfed by the organism. The mode of nutrition in amoeba is known as holozoic nutrition. It involves the ingestion, digestion and egestion of food material.
Detailed explanation-3: -By expanding their pseudopods, amoebas consume their meal. These elongated pseudopods enclose and devour living animals or small objects. It is known as phagocytosis or endocytosis.
