What characteristic do photosynthesis and combustion share?

Question

They both start with chemical energy
They both involve chemical change

Answer 1

Photosynthesis and combustion share the characteristic that they both involve chemical change.

In photosynthesis, plants convert carbon dioxide and water into glucose and oxygen using sunlight, resulting in a chemical transformation. In combustion, a fuel reacts with oxygen to produce energy, carbon dioxide, and water, also resulting in a chemical change. While photosynthesis stores energy, combustion releases energy, but both processes involve changes in the chemical composition of substances.
