However, Schrödinger observed that while the universe as a whole undergoes entropy, life somehow manages to reverse this process. Living organisms, he noted, survive through sucking order out of the entropy around them and organizing it in a way beneficial to them. They do this through the process known in biology as metabolism. Schrödinger called this process negative entropy (or negentropy) and saw it as the defining characteristic of life.
Metabolism. Negative entropy
