Photosynthesis is how plants get their energy. They take in carbon dioxide (CO2) and strip off the carbon to combine it with water (H2O). This produces carbohydrates such as glucose. The remaining oxygen (O2) liberated from the CO2 escapes away into the atmosphere. It’s this escaping oxygen that eventually led to the formation of the ozone layer, which protects land-based life from the Sun’s UV rays. The presence of the ozone layer enabled life on earth to leave the seas and spread over the land.
