OK, listen, there are several explanations for this, the first one is, you are born when the sperm meets the egg, which creates the Zygote. Afterwards, the zygote starts dividing into a bunch of stem cells. The stem cells slowly become the baby. Also, you get energy from food, which creates energy to make raw materials. For example: Eat an apple, and it becomes fat cells in your body if you don't burn it. If you do, Your Muscles will get stronger.
Carbohydrates, fats then proteins if neither of the other 2 are available.
The energy that a body needs comes from food that the body eats.
Sunlight is the primary source of energy for humans and all other living things. Also, glucose is a main source of energy (eating).
Food gives people and animals energy. Fortunatly for us humans, we don't need alot of food for alot of energy. Unfortunatly, animals have to eat two times more than we have to to get the great amout of energy it needs.
