n the stomach, muscles contract to
grind food into a pulpy mixture.​​mechanical​​ or
chemical

Answer 1

The process you are describing in the stomach pertains to **mechanical digestion**. The muscles contract to physically grind and mix the food into a pulpy mixture called chyme. **Chemical digestion**, on the other hand, involves the breakdown of food through enzymatic action and other chemical processes. In the stomach, both mechanical and chemical digestion occur, but the grinding of food specifically refers to mechanical digestion.
