In the very young earth the atmos. was mostly carbon dioxide. This caused the earth to have a very warm atmosphere. There was no life at that time on earth. It was a few billion years ago.
Where there are no components, there is air when it is located on Earth's surface. Our air has some carbon dioxide in it. So there is some carbon dioxide in an ipod. It is not necessary to the function of an ipod. If you burn an ipod, some carbon dioxide will be released, since the casing has some carbon in it.
nitrogen, oxygen, and carbon dioxide.
Carbon dioxide IS air
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
They take carbon dioxide out the air and turn it into oxygen, this is why we have life on Earth
Carbon dioxide is more dense than air.
do autotrophs remove carbon dioxide from the air
It depends on how you define air. Other planets in the solar system have atmospheres, but they have different compositions from Earth's atmosphere, which may or may not be called air. The gas planets have atmospheres made mostly of hydrogen and helium while Venus and Mars have atmospheres made mostly of carbon dioxide. The air we are familiar with is mostly nitrogen and oxygen. When Earth was young it likely had a carbon dioxide atmosphere as well, but through photosynthesis algae took carbon dioxide out of the atmosphere are replaced it with oxygen. More carbon dioxide was removed in bodies of water and deposited as carbonate rocks. The nitrogen, already present in the atmosphere, remained.
carbon dioxide is a air which comes from the plants
Air on Earth is mostly Nitrogen, followed by oxygen, and then carbon dioxide and trace gasses
Carbon dioxide is a greenhouse gas, that is, it has more than two atoms and so is able to capture the sun's heat as it radiates off the earth. So the carbon dioxide warms up and in turn, warms the surrounding air.
It means that there is more carbon dioxide (unbreathable air) gets in to are air
