$\displaystyle\blue{\underline{\underline{Different\:steps\:in\:the\:process\:of\: nutrition}}}$

There are five main steps in the process of nutrition in animals. They are :-

$\:\sf\underline\red{Ingestion\::-}\:$

"The mode by which the food is taken inside the body of the organism is called the ingestion "

This varies in different animals, some animals eat, some swallow and some suck the food. Cattle as well as human eat the food. Infants of human beings, humming bird , bees suck the food.

$\:\sf\underline\purple{Digestion\::-}\:$

"The process of breaking down of complex compounds of ingested food to simpler compounds is called digestion"

In a higher animal the digestion takes place in a long tube called alimentary canal.

$\:\sf\underline\green{Absorption\::-}\:$

The process of absorption of simple soluble food substance into the body cells is called absorption.

$\:\sf\underline\red{Assimilation\::-}\:$

The absorbed simple soluble food substances are transported to different parts of the body, where they are utilised for the production of energy for growth development and repair of body. This process is called assimilation.

$\:\sf\underline\purple{Egestion\::-}\:$

The part of food that is not digested and absorbed is pushed out of the body this process is called as egestion
