Question

what two raw materials are needed for photosynthesis?
water and oxygen
carbon dioxide and water
oxygen and nitrogen
sugar and carbon dioxide

Explanation:

Photosynthesis is the process by which plants convert light energy into chemical energy. The chemical equation for photosynthesis is \(6CO_2 + 6H_2O+light\ energy
ightarrow C_6H_{12}O_6 + 6O_2\). From the equation, it is clear that carbon dioxide (\(CO_2\)) and water (\(H_2O\)) are the raw materials. Oxygen (\(O_2\)) is a product, not a raw material. Nitrogen (\(N_2\)) is not involved in the basic photosynthesis reaction. Sugar (\(C_6H_{12}O_6\)) is the product of photosynthesis, not a raw material.

Answer:

Carbon Dioxide and Water
