respiration
No
carbon dioxide is needed in the chemical reactions to make glucose, the final product of photosynthesis.
Respiration - make carbon in carbon dioxide
Carbon dioxide is present in the air because plants need carbon dioxide to make food and without carbon dioxide plants would die and eventually the rest of the food chain.
No all chemical reactions do not make new things because if you do a chemical reactions using two of the same things e.g carbon dioxide + carbon dioxide you are not making anything else so no not all chemical reacions make new things
Roots do not make carbon dioxide.
Even a weak acid such as vinegar, added to limestone, will produce carbon Dioxide.
we would all die because of all the carbon dioxide in the air and no plants and trees to take in the carbon dioxide to make oxygen
Plants don't make carbon dioxide.
Chloroplasts enable plants to make carbohydrates from carbon dioxide and water through the process of photosynthesis. This organelle contains chlorophyll, which captures sunlight to drive the chemical reactions that convert carbon dioxide and water into glucose.
