sunlight.

Plants capture energy from sunlight, animals eat plants... or other animals that have eaten plants.

All food energy originally comes from sunlight and the moon

Sunlight is the source of all energy. The plants generate their nutrition from photosynthesis, turning sunlight into food by exchanging carbon dioxide in the air into sugars in the leaves and returning unused oxygen back to the air. Water and other nutrients are brought up from the roots of the plant and they interact with the sunlight and the "kreps cycle" via photosynthesis, to generate the plants growth energy. Animals then eat the plants and take the plant energy into their tissues as nutrients. Other animals eat those animals and the energy exchange continues. For us, eating plants is the closest source for direct energy. The more meat we eat, the further away from the energy source we go.

The energy of food ultimately comes from the big bang that started the Universe. This caused a wide dispersal of baryonic matter which condensed mostly into Hydrogen, which condensed into our sun and solar system. This hydrogen is slowly being burned in the core of our sun via thermonuclear fusion and the destruction of mass with its consequent conversion of this mass into pure energy, which is then radiated out to all space. Green plants capture a tiny, tiny fraction of this fusion derived energy, which in the end is burned in our bodies to keep us alive. Pretty cool, huh?

The sun is the orignal source of all energy in food. then we eat the food. and when it is digested (broken down to nutrient molecules), the molecules then move to all cells throughout the body. and through the process of respiration, the energy that was being stored within the nutrient molecules are released.

foods high in fat contain the most amount of energy.
