The equation shows the overall chemical reaction for photosynthesis, the process that plants use to make food from sunlight. Which statement explains why this is an endothermic reaction? 6CO2 + H2O + energy ---> C6H12O6 + 6O2
A) Water is one of the reactants.
B) A gas is released as one of the products.
C) The sugar dissolves in water.
D) Energy in the form of sunlight must be added.

During photosynthesis green plants use solar energy to produce fuel hence 'Energy in the form of sunlight must be added' that is option D is the correct option.

Why is photosynthesis an endothermic reaction?

Photosynthesis is an endothermic reaction because green plants use solar energy in the form of sunlight, along with water and carbon dioxide in the air, to produce their food in the form of glucose.

Endothermic reactions are chemical reactions where the reactants utilize heat energy from the surroundings to form products.

Since energy as sunlight is used in the photosynthesis reaction, 'Energy in the form of sunlight must be added' that is option D is the correct option.
