Question

How does increasing carbon dioxide affect photosynthesis?

Answer 1

Answer:

An increase in the carbon dioxide concentration increases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction, and so the rate of photosynthesis generally increases until limited by another factor.

Answer 2

Studies have shown that increased concentrations of carbon dioxide increase photosynthesis, spurring plant growth. ... While rising carbon dioxide concentrations in the air can be beneficial for plants, it is also the chief culprit of climate change.
