Question

Think about what happens to your food during digestion. The food material is broken down
into smaller pieces as you chew. Then it’s mixed with digestive enzymes in your stomach
that break it down into simple molecules to be absorbed by your body. Is digestion a
chemical change or a physical change, or both? Explain.

Answer 1

Both. Digestion is a chemical change because the food is broken down into smaller molecules, and a physical change because the food is broken down into smaller pieces.
