The Second Law of Thermodynamics states that "in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than that of the initial state." This is also commonly referred to as entropy.
A watchspring-driven watch will run until the potential energy in the spring is converted, and not again until energy is reapplied to the spring to rewind it.
A car that has run out of gas will not run again until you walk 10 miles to a gas station and refuel the car.
Once the potential energy locked in carbohydrates is converted into kinetic energy (energy in use or motion), the organism will get no more until energy is input again.
In the process of energy transfer, some energy will dissipate as heat.
Entropy is a measure of disorder: cells are NOT disordered and so have low entropy.
The flow of energy maintains order and life.
Entropy wins when organisms cease to take in energy and die.
