Assume you were testing O2 production inside a closed chamber with organic spinach leaves. Theoretically, does light influence O2 production inside the closed chamber (with organic spinach leaves)

Yes

Explanation:

The oxygen in plants is released when the water is broken down into the hydrogen protons and the oxygen gas. This hydrolysis of water takes place during the light-dependent phase of photosynthesis as it requires the light.

If we want to study the effect of light on oxygen production in a closed chamber then we will find that the absence of light will decrease the production of the oxygen gas and the increase in cellular respiration.  This is due to the fact that water hydrolysis is the result of the light-dependent phase.

Thus, Yes is correct.

the cost of mining is extremely low compared to the money earned from mining, creating income to improve the environment.
