Question

How to prove that we realease more carbon dioxide in respiration than the plants do in photosynthesis

Answer 1

In the respiration process we take in oxygen while we release carbon dioxide.
The amount of oxygen we take in is less than the carbon dioxide we released.
Whereas the plants take in this carbon dioxide in the process of photosynthesis and gives out oxygen. We release more carbon dioxide than plants do .

Answer 2

Photosynthesis also uses carbon dioxide faster than respiration produces it. Oxygen surplus is released into the air and unused glucose stored in the plant for later use. This is why plants are so important to human and other animals' survival.
