Photosynthesis absorbs energy from sunlight while it takes place. What type of reaction is it?
AAn exothermic reaction
BA combustion reaction
CAn endothermic reaction
DA precipitation one
Answer & Solution
Correct answer: C. An endothermic reaction
1. A reaction that absorbs energy in the form of heat or light is endothermic.
2. Photosynthesis absorbs energy in the form of sunlight while it takes place.
3. Photosynthesis is therefore an endothermic reaction.
4. Respiration and combustion both release energy, so those are exothermic reactions.
