Question

The digestion of food is an example of ________ reaction.

Answer 1

1. During the digestion of food, complex food substances like carbohydrates and fats are broken down into simpler forms. So, it is an example of a decomposition reaction.
2. Also, after decomposition, the simple substances are absorbed that release energy required in everyday activities. So, it is an example of an exothermic reaction as well.

Thus, the digestion of food is an example of decomposition and exothermic reaction.
