Photosynthesis and negative entropy production
Entropy balance in photosynthesis (PDF Download …
This describes , which evolved after the development of photosynthetic life on Earth began to raise the concentration of atmospheric oxygen. Oxygen is a poison to most life processes at the cellular level, and it is believed that aerobic respiration developed as a means to protect organisms from this peril. Those that did not adapt have literally gone underground and constitute the more primitive anaerobic bacteria.
For photosynthesis, entropy is decreasing, IOW ∆S<0
It requires a great deal of energy input in the form of sunlight, and the cumulative generation of entropy, first during the photosynthesis of glucose, and then through the respiration of glucose back into carbon dioxide and water (not to mention all of the other processes of life which go into circulating glucose through the biome) guarantees that the entropy always increases.
