Summary Introduction

To state:

Summarize how the laws of thermodynamics and the concept of entropy relate to a living organism.

Introduction:

The first law of thermodynamics state that the energy can neither be created or destroyed and second law state that the in any conversion of energy there is the loss of energy in the form of heat and the entropy of a closed system always increases.

It can be proved by taking an example that everyone eats food daily, but they do not gain the same amount of body weight. The food one eats is largely used to produce carbon dioxide and heat energy, some in repairing and rebuilding the tissues, neuron activity, and physical movement. The entropy is reduced in the living organism when small molecules assembled in higher structures, which releases the heat energy that increases the entropy of the environment.
