Teema: Re: Plants do throw off CO2 whenever they are not producing O. They make O when there is light, but at night they actually give off CO2.

Iamon lyme: Not as much CO2 as they absorb.. they use it to grow and lock it into their chemistry. If they didn't .... we would not be here, as plants are the reason for the decrease in CO2 levels/increase O2 that allowed animals to live on land.
