The process of breakdown of complex food particles into simpler absorbable substances is known as digestion. The different steps in the digestion process are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation.

The breaking down of food into a simpler form to provide energy is called digestion. The digestive system is made up of the mouth, food pipe, stomach, small intestine, large intestine, and anus.

Digestion is the process of breaking down complex molecules of food into simple and smaller food substances. These substances are easily absorbed into the blood plasma. The digestive path is a long tube that starts at the mouth where food is ingested and ends at the anus where the waste is egested.

The mode of taking food by an organism and its utilisation by the body is called as nutrition. The nutrients are required by living organisms for growth, repair and to obtain energy for performing life processes. There are two modes of obtaining nutrition- autotrophic mode of nutrition and heterotrophic mode of nutrition.
