Answer 1

Answer: (D)

Ingestion $\to$ Digestion $\to$ Absorption $\to$ Egestion

The process of nutrition involves different steps. There is ingestion of the food which is then digested. Digestion is a process which converts complex food substances to simpler ones. The digested food is then absorbed or assimilated and the waste products are removed by egestion. Nutrition involves ingestion, digestion, absorption, assimilation and egestion.

Thus, the correct answer is option D.
