Question

Digestion is a natural change. Explain.

Answer 1

• Digestion is a natural change because enzymes in the stomach and intestines break down the food i.e. large macromolecules into simpler molecules that can be easily absorbed by the human body.
• This process occurs on its own in our body.
• It is also an irreversible change because digested food cannot be converted into food that is being eaten.
