What is the Equation for photosynthesis? 6​ (a)   + 6​ (b)   (liquid) = ​ (c)   + 6 ​ (d)  

• CO₂ + sugar + H₂O --> O₂ + light
• _O2 + light + H₂O --> CO₂ + Sugar
• CO₂ + O₂ + H₂O --> Light+ Sugar
• CO2
• H2O
• C6H12O6
• O2

Based on the graph, how would you say CO₂ concentration affects the rate (speed) of photosynthesis in plants?

• Higher CO₂ levels always decrease the rate of photosynthesis.

• Higher CO₂ levels increase the rate of photosynthesis.

• Photosynthesis occurs only in the absence of CO₂.

• CO₂ concentration has no effect on the rate of photosynthesis.

As light intensity (amount/lumens) decreases in a forest, what will happen to the rate of PHOTOSYNTHESIS?

• Slow down with less light

• Continue at the same pace

• Speed up with the decreasing light

• Stop completely
