What is the primary gas used by plants during the process of photosynthesis?
Oxygen
Carbon Dioxide
Nitrogen
Hydrogen
How does increased carbon dioxide concentration affect the rate of photosynthesis?
Decreases the rate
No effect
Increases the rate
Halts the process
What is the relationship between the carbon dioxide concentration and the photosynthesis light saturation point?
Higher CO2 shifts the saturation point to a lower light level.
Higher CO2 does not affect the saturation point.
Higher CO2 increases the light saturation point.
Higher CO2 leads to decreased photosynthesis efficiency.
