Solution
Plants make their food by the process of photosynthesis.
- Photosynthesis is the conversion of light energy into chemical energy by plants. The chemical process is as follows: water and carbon dioxide react to produce glucose and oxygen. Photosynthesis is certainly a chemical change since new chemical species are produced.
- Chemical change: A change that alters some specific properties of matter, by bringing about a change in its molecular composition.
