A scientist grows microscopic algae from ocean plankton in the light. The algae use chlorophyll to make glucose and oxygen from carbon dioxide and water.
Which statement explains how this endothermic process changes the absorbed light energy?
Chemical energy in carbon dioxide is transferred to glucose while light warms the algae.
Light energy absorbed by chlorophyll is destroyed as it is used to split water molecules.
Light energy absorbed by chlorophyll is transferred into chemical energy stored in glucose.
Light energy absorbed by chlorophyll remains in chlorophyll instead of entering the glucose.
