I thought (maybe i'm wrong?) that they still respire... so taking in Oxygen, and breathe out CO2... and that photosynthesis is a different mechanism that extracts CO2 from the air and produces O2
Pretty sure I read somewhere that some trees can take around a decade to grow to the point where they become net extractors of CO2?
Life on earth is made mostly by carbon (and water) in various forms. That carbon mostly comes from the CO2 used by photosynthesis, and is passed up the food chain to all life.
Vast majority of plants don't quite have a way of eating other things with carbon, so the carbon that they give off has to have come from their own photosynthesis.
