Which gas is more important? *
CO2
Oxygen
Both
None

Both are important.

Explanation: Carbon dioxide, also called CO2, is found in water as a dissolved gas. It can dissolve in water 200 times more easily than oxygen. Aquatic plants depend on carbon dioxide for life and growth, just as fish depend on oxygen. Plants use carbon dioxide during the process of photosynthesis. So therefore, they are both important for survival. Plants need carbon dioxide and other organisms (animals and humans) need oxygen. Hope this helps ^-^.
