      Plants use CO2 and sunlight to make energy for them to live and grow. The waste products from the process are oxygen and water.

      Trees and plants use CO2 – the process of photosynthesis uses CO2 to convert the sun’s energy to energy that the plant can use. That’s why plants and trees are so good for the environment, they “soak up” CO2.
      And humans use CO2 to make fizzy drinks fizzy.
      I can’t think of any other uses though…
