we breath out a little oxygen aswell
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.
carbon dioxide
No, you cannot breathe carbon dioxide. It is a waste gas that can be harmful to humans if inhaled in high concentrations.
Humans breathe in oxygen and breathe out carbon dioxide. Trees "breathe" out oxygen.
Humans breathe in oxygen, which plants produce, and breathe out carbon dioxide, which plants take in.
No, Carbon Dioxide is the gas that plants use in Photosynthesis to transform it into oxygen for us to breathe.
Carbon dioxide . It is part of the Carbon and Oxygen cycles. Humans ( all animals) breath in ( inhale) oxygen . It is used internally in the animated organism. It is then breathed out ( exhaled) as carbon dioxide. Carbon dioxide is a heavy gas, and 'falls' to the ground. Whereupon , it is absorbed by green plant life. Then under the process of photosynthesis within the plant , the carbon dioxide is broken down in to oxygen and carbon. The oxygen is released back into the atmosphere, and the carbon is kept in the plant as biomass.
plants inhale carbon dioxide and breath out oxygen. Its the opposite of what humans do, we breathe in oxygen and breathe out carbon dioxide.
Humans, and actually all other animals, breathe out carbon dioxide. Plants take in this carbon dioxide and combine it with water and sunlight to make food in a process called photosynthesis. Luckily, a byproduct of this process is oxygen, which humans and other animals breathe in. Then we breathe out carbon dioxide, and the wondrous cycle continues.
Humans take in oxygen and breathe out carbon dioxide.
No, humans do not breathe in nitrogen as a part of the air they inhale. The air we breathe is mostly made up of oxygen, with a small amount of other gases like nitrogen and carbon dioxide.
Humans breathe out carbon dioxide, the whole world runs in a motion, for example plants breathe carbon dioxide, we breathe in oxygen. Even fish breathe oxygen. They take the oxygen out of the water. So we breathe in what plants breathe out and plants breathe in what we breathe out.
