How Photosynthesis Works

Photosynthesis is the process in which autotrophs convert light energy from the sun into chemical energy in the form of organic compounds, mainly carbohydrates.

Most all autotrophs use the process of photosynthesis. Since photosynthesis involves a complex series of chemical reactions, where the product of one reaction is consumed in the next reaction, it is referred to as a biological pathway. There are two main cycles in photosynthesis, the light cycle, and the dark or Calvin cycle.
