Ezra eats a cheese sandwich for lunch. Cheese contains a lot of protein, and bread is mostly starch. Ezra plans to play basketball later in the afternoon. He isbreathing normally. What does Ezra need from the food he ate and the air he breathes so that he can play basketball? How do Ezra’s body systems work together to get the molecules he needs into his cells? How do his cells use these molecules to release energy for his body to run?

i- i think he needs the vitamins-? im really bad at this stuff- but i think he needs the vitamins cause he already has protein.And maybe he should drink water to digest it correctly before he had played. i dont know if im helping.- tell me if i did-

Explanation:

the more fit you are, the faster the recovery. your heart rate drops most sharply in the first minute after you stop exercising; it should then fall about 20 beats a minute—a drop of less than 12 beats a minute is considered abnormal. this “recovery heart rate” is measured as part of an exercise stress test.
