Yes. The air is 21% oxygen which is what humans run on. It is 79% nitrogen which we filter out. I learned this today in Health class.
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.
You need to breathe in oxygen and you need to breathe out carbon dioxide.
They 'breathe' through the stomata on both surfaces of the leaf. The stomata are extremely tiny 'holes' that you can only see under a microscope. They are usually found on the underside of the leaves.
"Air" is the most important cycle that exists between the atmosphere and earth, e.g. a sustained cycle between plants on earth and the air we breathe, and humans. Air is important as a natural resource because we AND plants must breathe. Plants use carbon dioxide which humans breathe out. Humans breathe in oxygen, which plants give off. Without these two components of "air" or if these became out of balance, both plants and humans would die.
Yes, partially. Trees give us oxygen (which is a gas we breath). Most of the air in our atmosphere is made up of nitrogen (around 78%). Oxygen, carbon dioxide and water vapor make up the majority of the rest of the air, of which trees only give us oxygen. Oxygen is the second most common element in air though; so I would still have to say yes. Humans and most animals on our planet breathe in oxygen and breathe out carbon-dioxide. Yet trees breathe in the carbon-dioxide we breathe out and breathe out oxygen which we need to breathe in. Of course don't give us all our oxygen either. Most of the oxygen replenishment comes from sea weed (or sea algae). But the simple answer to your question is yes. Oh, and Al Gore is a liar. That is always a good ending to a good answer about the air in our atmosphere.
Humans breathe in oxygen and breathe out carbon dioxide. Trees "breathe" out oxygen.
On average, humans breathe in about 21% oxygen from the air.
to live and
They breathe in oxygen like humans.
Oxygen is essential to humans. We breathe it in.
No.
Humans take in oxygen and breathe out 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.
It reduces the oxygen in the area because humans breathe in oxygen and breathe out nitrogen.[plants breathe in nitrogen and breathe out oxygen for humans.so without trees.Humans will not survive
Humans inhale oxygen and exhale carbon dioxide.
Terrible grammar. Either the asker does not speek English or is mentally challenged. I will slowly answer this question the best that I can. Humans... use oxygen... to breathe... If humans could not breathe they could not do anything industrial! That is "how humans you use oxygen in industry". They breathe it. You should try it. Your brain could use some oxygen numbnut!
Absolutely. It's what we breathe.
