Photosynthesis

Photosynthesis allows plants, algae and certain bacteria to turn sunlight into chemical energy. The amazing feat is achieved because sunlight can fuel a reaction between water and carbon dioxide that, in turn, produces carbohydrates (simple sugars) and oxygen. Here is the latest news on photosynthesis, including the oldest evidence of it on Earth and how blocking photosynthesis on a large scale can affect food chains.
