While in human beings, the food (which is complex substance) is taken inside the mouth and undergoes a complex process of digestion and absorption in the digestive system.

Detailed explanation-2: -Both Amoeba and human beings are living organisms. Both are made of similar living components and macromolecules. Both are heterotropic or have a holozoic mode of nutrition.

Detailed explanation-3: -Holozoic mode of nutrition involves the ingestion of food material. The process of holozoic nutrition further comprises digestion, absorption, assimilation of the food, egestion. Humans and amoeba take in nutrition by holozoic mode.

Detailed explanation-4: -Answer: Similarity: Both amoeba and human beings follow the holozoic type of nutrition. Difference: Humans intake food through buccal cavity.
