Document Summary
We can define energy as the capacity to do work. Chemical gradient, gravity, friction or moving a chemical reaction towards completion. Energy can be transformed between one form and another. Energy possessed by an object because it is in motion. Photon of light or electricity all the energy that comes into a plant are photons, where plants can harness. Due to the force of gravity; pulling it down. Energy can not be created or destroyed, but only converted to other forms. Principle of the conservation of energy through transforming energy. The amount of energy in the universe is constant. The total disorder (entropy) of a system and its surrounding will increase. Energy will always become more spread out driving force of diffusion; spontaneous process simply because the energy is spreading out. Energy transfer in a biochemical reaction is also inefficient. A certain % of the energy is lost as entropy.
