Remember, put this into your own words. Your education system will detect you copied/paraphrased from an online source.
Photosynthesis uses certain things to produce sugars, oxygen, etc.
It uses these things: Sunlight, water, carbon dioxide.
Therefore it uses the energy from the sun.
This supports the law of conservation which states energy cannot be created, nor destroyed. It re-uses energy, like the sun's light.
Hope this helped!
