After sophie eats, her body breaks down the food to use as an energy source when she runs. this is an example of which type of energy conversion?

chemical to mechanical

mechanical to thermal

thermal to chemical

thermal to mechanical

chemical to mechanical

Explanation:

Chemical energy is the energy stored in the bonds of molecules.

Mechanical energy is the energy possessed by a body by virtue of its position and motion.

Thermal energy is the energy possessed by a body by virtue of its temperature.

According to law of conservation of energy, energy remains conserved. It only transforms from one form to another. When food is oxidized, the chemical energy stored in the bonds of food  converts to kinetic energy which is the energy possessed by an object by virtue of motion.
