Sunlight Provides Solar Energy

Photosynthesis produces carbohydrates and oxygen, both of which are utilized by the majority of living things. Photosynthesis uses solar energy in the visible-light range; the photons of this range contain the right amount of energy to energize the electrons of chlorophyll molecules. Specifically, chlorophylls a and b absorb violet, blue, and red wavelengths best. This causes chlorophyll to appear green to
