Answer:
D Solar energy is needed for photosynthesis, and chemical energy in the form of glucose is needed for cellular respiration.
Explanation:
Photosynthesis is a physiochemical process by which photosynthetic organisms transform light energy into chemical energy in the form of reducing power (as NADPH) and ATP. These chemicals are used to drive carbon dioxide fixation.
Cellular respiration is an oxidative process in which free energy released from organic compounds is used in the formation of ATP. Carbohydrates are most commonly used as respiratory substrate.
