do plants use carbon dioxide
Plants use the CO2 waste gas from animal respiration to make glucose for chemical energy for cells and they put out oxygen into the atmosphere. Oxygen is taken in by animals, used to break down glucose to make ATP for energy for cellular processes, and giving out CO2 which plants take in for photosynthesis.arbon dioxide is used by plants during photosynthesis to manufacture glucose; this is where the carbon in the equation comes from.
