Answer:
a gas produced during photosynthesis
Explanation:
during photosynthesis plants use carbon dioxide, water and sunlight to make sugar (glucose) and a waste product, oxygen gas.
the equation of this process can be:
6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2.
carbon dioxide + water + light → glucose + oxygen
