Question

multiple choice question
which of the following is not an ingredient that plants need for photosynthesis?
a.water
b.light
c.nitrogen
d.carbon dioxide
which answer did you pick and why?

Explanation:

Photosynthesis is the process by which plants convert light energy into chemical energy. The equation for photosynthesis is \(6CO_2 + 6H_2O \xrightarrow{light} C_6H_{12}O_6+6O_2\). As we can see from the equation, water (\(H_2O\)), light, and carbon dioxide (\(CO_2\)) are required. Nitrogen (\(N_2\)) is not used in the photosynthesis reaction.

Answer:

C. Nitrogen
