Potential energy is when you do work against a conservative force. Examples are gravitational potential energy; the stored energy in a spring; chemical energy; and nuclear energy.
Energy is stored in the cells. The cells travel around the organism (or a living system) and give off, or produce, energy.

An example is sand on a beach stores the energy from the sun in it. A stretched spring has stored potential energy that is released when the spring is returned to its unstretched state.

ATP is what cells use to perform most cellular work. Energy ready to be spent exists in this form. Saccharides (sugars) are used to create ATP in the process in the process of cellular respiration. Lipids(fats) are the back up energy source for when sugar molecules are running low.
1. Micro-organisms help in some cases 2. Micro-organisms are small
Carbohydrates take in and give out energy. The energy is stored in ribosomes. Ribosomes also carry protein which creates energy and distributes it.
