Which gas do plants need to perform photosynthesis?
Correct answer: Carbon dioxide

Bigkev
carbon is actually plant food, and we're made up of some as well, global temperature has only risen 1 degree in over 100 years.

Kapi
Plants use CO2 as food and produce O2 for humans to breathe

And all that just happened by itself. I don’t think so

BigBrain
Plants take in co2 and release oxygen which we breathe in. We then release co2 which the plants take in and the cycle repeats
