WILL GIVE BRAINLIST, POINTS, STARS, ETC.

Can someone help me reword this please? I don't like how I did it.

Photosynthesis turns carbon dioxide and water into oxygen and carbohydrates, therefore a chemical change happens. It is also an endothermic reaction because energy needs to be inputted in order for photosynthesis to occur. The energy input is then stored in the bonds of the glucose that were formed as a result of photosynthesis.
