Answer 2

Answer:

It is necessary to break down the food we eat from a complex to a simpler form because ​our body is unable to digest the complex molecules of food.

Explanation:

• This process of breaking down the complex food molecules into a simpler form to digest is known as Digestion.
• In the process of digestion, our digestive system converts the complex food molecules into simpler forms such as glucose or sugars, amino acids (that constitute the protein), and fatty acids (that constitute fats) for energy, growth & repair.
• The small intestine absorbs the broken-down food from the bloodstream and then the important nutrients are carried to every cell present in the body.
• The process of digestion consists of 4 basic steps-

1. Ingestion
2. Digestion
3. Absorption
4. Egestion
