The law of conservation of energy is a law of science which states that energy can neither be created nor destroyed - only converted from one form of energy to another.

In 1842, Julius Robert Mayer discovered the Law of Conservation of Energy.

Claude Bernard was a French physiologist, who first recognised plant stomata opening and closing to maintain homeostasis.
