Carotenoids are antioxidants and may protect the skin from uv light but studies are scarse....

I"ll give you a clue
http://en.wikipedia.org/wiki/Carotenoid
Introduction, paragraph 2 and Section 2 physiological effects should answer most of your question. From that you can explore deeper using pubmed and recent literature.

hello ,
i want say about Photosynthesis. Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. 6H2O + 6CO2 ----------> C6H12O6+ 6O2
i like chating
