While only weighing about 2% of the total body weight requires 25% of the total food/energy consumed....

Physics examines how matter, energy, time, and space interact. About 300,000 years after that matter and energy started combining to form atoms which then formed complex molecules and this becomes Chemistry. About 4 billion years ago even more complex structures started to form call organisms “living” which is Biology....
