No.
we also exhale water(h2o) along with carbon dioxide. All the constituents of the air we inhale are in the air we exhale. The proportions differ because of the gas exchange in the lungs.
Hyenas, like all mammals, breathe in oxygen from the air and release carbon dioxide as a waste product of respiration. They have lungs that extract oxygen from inhaled air and expel carbon dioxide when they exhale.
All of the air in the lungs gets exchanged with oxygen upon each breath. We exhale carbon dioxide and inhale oxygen.
All plants inhale carbon dioxide and exhale oxygen.
All animals are effected. We all release carbon Dioxide as we exhale, and then the trees and plants surrounding absorb the Carbon Dioxide, and release oxygen.
Like all animals, they inhale oxygen and exhale carbon dioxide.
The gas that is taken in by animals is oxygen. Animals absorb oxygen and exhale carbon dioxide. Plants take in carbon dioxide and let out oxygen.
because they have to let all the bad stuf out
When you exhale, you actually release oxygen, nitrogen and other gasses. But most of all you release more carbon dioxide. People often think that the lungs must be full of carbon dioxide but they are not. The percentage of gas in the lungs that is highest is nitrogen. It isn't used by your body but is important in keeping your lungs inflated. But all-in-all, you exhale more carbon dioxide than you inhale.
Yes, but this has essentially no impact on global warming. The reason is that the carbon you exhale derives primarily from organic matter which grew via photosynthesis--taking carbon from the air. So the amount of CO2 you exhale remains in balance with the carbon taken in by the plants grown as food crops to satisfy your appetite. The seven billion people on earth cumulatively could not exhale enough CO2 to exceed earth's capacity to naturally absorb it all.
Mammals inhale oxygen and exhale carbon dioxide, as do all animals.
After you breathe air IN, your body uses some (but not all) of the oxygen in it. A lot of that oxygen that your body uses get converted to carbon dioxide, and it's added to the air that you breathe out. So your exhaled air has a greater concentration of carbon dioxide than fresh air has.
