Solution
The correct option is A Amoeba, Paramecium, Humans
Holozoic nutrition is characterized by the ingestion and digestion of liquid or solid food particles inside the body.
The mode of nutrition in amoeba is known as holozoic nutrition. It involves the ingestion, digestion, and egestion of food material. Amoeba does not have any specialized organ for nutrition. Its entire process is carried through the body surface with the help of pseudopodia.
In case of Paramoecium the oral groove of fuses forms a membrane that takes food particles first to the cytostome and then to the pharynx. It forms a food vacuole so the nutrition of paramecium is holozoic which is it engulfs full food particles which are then digested.
The nutrition in human beings is holozoic because they take food in complex and convert it into simpler substances through some biochemical processes inside their bodies. This is carried out by the specialized digestive system and the enzymes secreted by the associated glands.
