The movement of energy between living organisms is a matter of atoms, molecules and compounds being built into larger molecules or being broke into smaller ones. Reviewing the two equations for energy transference, which one is building energy? 6CO2 + 6H2O + energy   -------->  C6H12O6 + 6O2   C6H12O6 + 6O2    --------->   6CO2 + 6H2O + energy

Introduction :

Energy is required for life functions inside every cell of every living being. Energy is necessary for the breakdown and reconstruction of molecules as well as the transport of many molecules across plasma membranes. All of life's activities require energy. A significant amount of energy is also lost to the environment as heat.

The chemical energy required by organisms is derived from food. Food is composed of organic molecules whose chemical bonds store energy. There are two sorts of creatures that obtain food for energy: autotrophs and heterotrophs.
