Explanation:

Cellular respiration is what gives energy to all things, and since you need energy to live, Cellular Respiration is constantly happening. Your body takes in food and digests it in your stomach to give the food to your cells through Blood Transport. When the cells use this food to power themselves, they release energy which in turn powers you. That is why you become hungry, because your cells are in need of more nutrients to make sure you can survive
