is the following an exothermic or endothermic rxn? if exothermic, what is the form in which kinetic energy is released and if endothermic, what is the kinetic energy absorbed?

1. chem rxn that takes place in a glow stick in which 1,2-dioxetanedione decomposes into carbon dioxide, producing light.
2. photosynthesis in which leaves of the green plants take in carbon dioxide and water and in the presence of sunlight, convert them into glucose and oxygen gas.

thanks so much! i wrote for 1. endothermic and 2. exothermic are they wrong?
