Entropy

A quantitative measure of the disorder of a system and inversely related to the amount of energy available to do work in an isolated system. The more energy has become dispersed, the less work it can perform and the greater the entropy.

Biological systems maintain high internal organization, carry out numerous work cycles, and counteract increasing disorder through the consumption and transferal of energy. However, biological systems do not violate the second law of thermodynamics. Rather, the increased internal organization of the organism results in decreased external order.
