Which system takes in food and breaks it down into nutrients?

Digestive System

Explanation:

The digestion process begins in the mouth, where food is reduced to smaller particles by chewing and the action of salivary enzymes.

In the stomach, food particles are further reduced due to the action of hydrochloric acid (HCl) and protein-breaking enzymes.

After that, the food goes to the small intestine, where it acts the bile (from the liver) that reduces the fat particles, as well as enzymes that finish the breakdown of proteins and carbohydrates.  The nutrients are then absorbed and transported to the bloodstream.

Finally, the rest of the food reaches the large intestine, which absorbs water and forms the feces that will be excreted.
