Life Processes

The five steps involved in the process of nutrition in human beings are ingestion, digestion, absorption, assimilation, and egestion.

Ingestion is the process of taking in food, while digestion is the process of changing the complex food taken in into a simple, absorbable form by the action of certain enzymes.

Digestion is necessary for the body to use food because it converts the food into simple, soluble forms that can be absorbed by the body.
