​Who Needs Food?

  • Plants make the food they need to survive and grow by carrying out photosynthesis. This food contains energy stored as matter. The matter in the food is made up of sugars and comes from the carbon dioxide in the air and water. The energy stored in the sugars was once light energy from the sun.
