Second law of thermodynamics states that the degree of disorder always increases spontaneously in an isolated system or in the universe as a whole, it can never decrease.
The measure of the disorder in a system is called the entropy of a system.[1]
If a system (for example, an organism) is not isolated, its entropy can decrease, provided that the entropy of its surroundings increases.
