What waste product of photosynthesis allows you to live on earth?

asambeis [7]

Photosynthesis allows plants to take in sunlight, water, and carbon dioxide to make energy for themselves, a type of sugar called glucose.

Glucose = $C_{6} H_{12}O_{6}$

The other thing that is made from photosynthesis is oxygen.

Without oxygen, we would not be able to live on earth.

Hope this helps!
