Respiration of air-breathing animals, flatulence (especially bovine), volcanic outgassing, and decomposition of plants, to name a few.
No. helium does not produce carbon dioxide
Yes, carbon dioxide can be a natural gas.
One natural process that adds carbon dioxide to the air is the process of respiration by plants, animals, and microorganisms. During respiration, these organisms release carbon dioxide as a byproduct. Additionally, volcanic eruptions also contribute to the release of carbon dioxide into the atmosphere.
Algae are plants and produce oxygen from carbon dioxide when exposed to sunlight by photosynthesis. At night they produce carbon dioxide though cellular respiration.
Respiration (breathing) and combustion (fire). Both processes combine oxygen and some form of fuel to produce carbon dioxide, water, and energy.
The plants use carbon dioxide and give oxygen.

Burning (combustion) of organic substance will produce waste Carbon Dioxide. Also metabolic processes in living things produces waste Carbon Dioxide.
The digesting of food is more likely to cause methane than carbon dioxide. Carbon dioxide is liberated when dissolved food is used in biological processes at the cellular level as carbon compounds combine with oxygen to produce energy.
carbon dioxide and water
No. helium does not produce carbon dioxide
Ethyl alcohol fermentation and the Krebs cycle >>NovaNet
Yes, forest fires do produce carbon dioxide.
Yes, carbon dioxide can be a natural gas.
Almost all fuels produce carbon dioxide when burnt, but only fossil fuels such as oil, coal and natural gas actually add to the amount of carbon dioxide naturally present in the atmosphere.
All metabolic processes of animals produce carbon dioxide. This is collected from the cells by your blood cell and released to the atmosphere from your lungs when you breathe out.
