Breathing. Birds, do it, bees do it, even educated trees do it. But, only plants can make sugars from the carbon dioxide byproduct and at the same time expel oxygen during photosynthesis. This amazing skill has intrigued scientists for decades but separating out the carbon dioxide inputs and outputs while keeping tabs on oxygen levels has always proved difficult.
