Trees and other plants produce oxygen, not CO2. And walking at night is completely irrelevant in any case.
No. helium does not produce carbon dioxide
Yes, forest fires do produce carbon dioxide.
This happens because the equilibrium between carbonic acid and carbon dioxide shifts to produce carbon dioxide.
Animals produce carbon dioxide. Animals produce carbon dioxide
it produces heat
Algae are plants and produce oxygen from carbon dioxide when exposed to sunlight by photosynthesis. At night they produce carbon dioxide though cellular respiration.
Because trees consume carbon dioxide and produce oxygen.
Yes. Plankton produce carbon dioxide during cellular respiration.
because plants need carbon dioxide that we produce and animals and people need oxygen that plants produce
no because they need to live with it do no
carbon dioxide :)
Yes. Burning carbon or a carbon compound will produce carbon dioxide.
