Energy and Order in Biological Systems The concept of entropy entropy and and the second law of thermodynamics suggests thermodynamics suggests that systems naturally progress from order to disorder. If so, how do biological systems develop and maintain such a high degree of order? Is this a violation of the second law of thermodynamics?
Order can be produced with an expenditure of energy, energy, and the order associated with life on the earth is produced with the aid of energy from the sun.
Index Second law concepts Heat engine concepts
For example, plants use energy from the sun in tiny energy factories called chloroplasts.. Using chlorophyll in the process called photosynthesis chloroplasts photosynthesis,, they convert the sun's energy into storable form in ordered sugar sugar molecules. molecules. In this way, carbon and water in a more disordered state are combined to form the more ordered sugar molecules. In animal systems there are also small structures within the cells called mitochondria which mitochondria which use the energy stored in sugar molecules from food to form more highly ordered structures. A tree converts disorder to order with a little help from the Sun
