Question

is Photosynthesis a decompisition reaction

Answer 1

$\huge\mathbb{Answer:-}$

No, photosynthesis is an endothermic reaction and not a decomposition reaction.

This is because reactions in which compounds split into two or more than than two simpler substances are termed as decomposition reactions, but in the case of photosynthesis, carbon dioxide, water along with sunlight energy combine or react to produce glucose and release oxygen.

Thus, photosynthesis is not a decomposition reaction but an endothermic reaction ad sunlight energy is absorbed during the process by photosynthetic autotrophs.
