The primary control of carbon dioxide levels in the atmosphere is the balance between natural processes such as photosynthesis and respiration, as well as human activities like fossil fuel combustion and deforestation. Oceans also play a significant role by absorbing CO2 from the atmosphere. Additionally, geological processes, including volcanic eruptions and the weathering of rocks, contribute to the carbon cycle. Overall, the interplay between these natural and anthropogenic factors determines atmospheric CO2 concentrations.
Venus' atmosphere is primarily composed of carbon dioxide (96.5%) with traces of nitrogen and sulfur dioxide.

The more carbon dioxide in the atmosphere, the higher the temperature.
The amount of carbon dioxide a person produces
The amount of CO2 in the atmosphere is increasingly drastically, attributed primarily to human activities.

Into the atmosphere as carbon dioxide.
No, car exhaust is primarily composed of carbon monoxide, nitrogen oxides, and hydrocarbons, with smaller amounts of carbon dioxide and other pollutants.
Carbon is stored in the atmosphere primarily as carbon dioxide (CO2) molecule.
Forest fires increase the amount of carbon dioxide in the atmosphere
No, the amount of oxygen in the atmosphere is much greater than the amount of carbon dioxide. The current levels of carbon dioxide are approximately 0.04% of the atmosphere, while oxygen levels are around 21%.
The amount of carbon dioxide exhaled is always greater than the amount inhaled because part of the oxygen inhaled is converted into carbon dioxide by metabolic processes of digestion, while any carbon dioxide inhaled remains unchanged in the body and is always exhaled again.
Plants primarily obtain the majority of their carbon from carbon dioxide in the air through the process of photosynthesis.
The amount of carbon dioxide dissolved in the plasma is typically around 1.2-2.0 millimoles per liter.
