The amount of carbon dioxide a person produces
carbon dioxide :p
Respiration :)
Solid carbon dioxide is not dangerous but avoid contact with skin and eyes.
The carbon dioxide level fluctuates during a single year due to seasonal changes in plant growth and decay, which affect the amount of carbon dioxide absorbed and released into the atmosphere.
of course :) :)
Forest fires increase the amount of carbon dioxide in the atmosphere
Carbon Dioxide because without water you die and with carbon dioxide(concentrated in large amounts) you will have trouble breathing, or possibly die.
carbon dioxide
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.
Respiration, breathing, has no effect on the amount of carbon dioxide in the atmosphere. This is part of the natural carbon cycle. Burning fossil fuels (coal, oil and natural gas) releases carbon dioxide that has been hidden away for millions of years. This extra gas is increasing in the atmosphere.
