Energy cannot be created or destroyed, only transferred or transformed.

        i.            First Law of Thermodynamics (Law of Conservation of Energy): This law states that energy cannot be created or destroyed in an isolated system; it can only be transferred or transformed from one form to another. In the context of biology, this means that energy within a biological system is neither created nor destroyed but is instead converted from one form (e.g., chemical energy) to another (e.g., mechanical energy or heat).

      ii.            Second Law of Thermodynamics: This law states that in any conversion of energy from one form to another, there is always a decrease in the amount of useful energy. Some amount of energy will always be lost in the form of heat.
