Humans breathe in whatever happens to be in the air when they breathe in. If there is carbon dioxide then they will breathe it in as well as nitrogen and oxygen. However they only use the oxygen for respiration so they breathe out everything else with extra carbon dioxide.
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.
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.
The primary gas that humans exhale when breathing is carbon dioxide.
Humans have greatly increased the level of carbon dioxide in the atmosphere. This is primarily due to the burning of fossil fuels for energy production, transportation, and industrial activities. This increase in carbon dioxide is a major contributor to global warming and climate change.
carbon dioxide
Animals exhale carbon dioxide and inhale oxygen just as humans do.
Humans inhale oxygen and exhale carbon dioxide.
carbon dioxide
plants inhale carbon dioxide and breath out oxygen. Its the opposite of what humans do, we breathe in oxygen and breathe out carbon dioxide.
Yes humans inhale oxygen but exhale carbon dioxide.
plants and trees inhale carbon dioxide and exhale oxygen. The opposite of humans.
Photosynthesis creates oxygen as a byproduct which we humans then inhale, and exhale carbon dioxide which is what the plants "inhale."
plants inhale carbon dioxide and exhale oxygen
Humans inhale oxygen, and breath out carbon dioxide. It is like a cycle.
No, humans do not breathe in carbon dioxide. We inhale air that contains oxygen and exhale carbon dioxide as a waste product of respiration. Breathing in too much carbon dioxide can be harmful to our health.
Carbon Dioxide?
Most living animals inhale oxygen and exhale carbon dioxide plants try to compensate for that so they can live on earth by soaking up the carbon dioxide for photosynthesis and excreting oxygen therefore we are inhaling the carbon dioxide we create
