The don't. Breathing rate increases fairly dramatically when exercising, unless said person is extremely fit (e.g. Lance Armstrong at his peak) and/or not doing any over;y exerting work.
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!
when you breathe out, plants breathe in.
Humans breathe in oxygen and breathe out carbon dioxide. Trees "breathe" out oxygen.
The same air that we humans breathe in.
just breathe slowly.
They breathe through their mouth and nose and have lungs, just like humans. :)
since humans talk when they breathe out and dogs do it when they breathe in this is the main reason why humans talk and they bark
False. When your body requires more oxygen, you tend to breathe faster in order to increase oxygen intake and remove carbon dioxide more efficiently. This helps to meet the increased demands of your body during exercise or other activities that require high levels of oxygen.
they breathe just like humans, out of their nose and mouth
Oxygen is essential to humans. We breathe it in.
No, humans do not need nitrogen to breathe for survival. The air we breathe is primarily made up of oxygen, with only a small amount of nitrogen.
through their gills.
