What are the steps of nutrition in animals?

The steps of nutrition in animals are a series of processes through which food is taken in, broken down, absorbed, and utilized by the body. These steps ensure that animals receive energy and essential nutrients.

The first step is ingestion, where food is taken into the body through the mouth.

The second step is digestion, in which complex food substances are broken down into simpler, soluble forms with the help of digestive enzymes.

The third step is absorption, where the digested nutrients are absorbed into the bloodstream through the walls of the intestine.

The fourth step is assimilation, where the absorbed nutrients are utilized by cells for energy, growth, and repair.

The final step is egestion, which involves the removal of undigested and waste materials from the body.

These steps together complete the process of nutrition in animals.
