Photosynthesis is an example of
A. an exothermic reaction.
B. an endothermic reaction.
C. a reaction that gives off heat.
D. a reaction that emits energy.

Photosynthesis is an example of an endothermic reaction as it requires energy, specifically sunlight, to convert carbon dioxide and water into glucose. This process captures energy rather than releasing it, making it critical for life on Earth. Understanding this process highlights the importance of energy transformation in biological systems. ;
