Correct! Wrong!

Engulfing food by the cell in solid or liquid form is called holozoic nutrition.

Holozoic nutrition is a type of heterotrophic nutrition in which the cell ingests liquid or solid food particles. This kind of nutrition is found in unicellular organisms such as amoeba as well as in multicellular animals such as humans.  In the holozoic type of nutrition, liquid or solid food particle is taken by the cell and then further broken down into small fragments. The animals get energy as well as organic building blocks by ingesting and then digesting the food particles.

Several stages of holozoic nutrition are (i) Ingestion (intake of food through the mouth or phagocytosis), (ii) Digestion (physical breakdown of large food particles into small particles, and enzymatic breakdown of complex molecules into simple molecules), (iii) Absorption (transport of the digested products into the body or cytoplasm). (iv) Assimilation (utilization of the absorbed molecules in different metabolic processes) and (v) Egestion (removal of undigested material).
