We breath in air (left), breath out (right) which is approx;
Nitrogen 79% -----------------------Nitrogen 79%
Oxygen 20% -------------------------Oxygen 16%
Argon 1%--------------------------------- Argon 1%
Carbon dioxide 0.0384% ---carbon dioxide 4%
We breath out air with a higher level of carbon dioxide and a lower level of oxygen; breathing also results in loss of water from the body, exhaled air has a relative humidity of 100% (with trace's of methanol and other organic compounds generated inside the body).
humans breathe in oxygen and breathe out carbon dioxide
Cabon dioxide
we breathe out 16.4% oxygen,4% CO2,78% nitrogen.
Animals breathe a mix of gases including;NitrogenOxygenCarbon dioxideWaterArgon
Oxygen. of course!! All living beings need oxygen to live on earth.
Arboreal animals breathe in the same manner as most other animals. They use the nostrils and the mouth to breathe in and breathe out.
Marine animals breathe through the nose by inhaling and exhaling. :)
No. Nothing can breathe fire.
so that we can breathe and human and animals can have it get in there longs to help them breathe
Oxygen is used to help people breathe in and out
Humans/animals take in oxygen and breath out carbon dioxide during respiration. Plants do the opposite during photosynthesis.
Cutaneous gas exchange.
oxygen
Plants breathe in a gas called carbon dioxide and then they breathe out the gas called oxygen which is what we breathe in! Also there is most likely a type of living thing which no human has ever discovered and so there may be milllions of kind of living things that may not breathe in oxygen - they might not even breathe in a gas!
Oxygen is the gas humans and animals need to breathe in.
when you breathe out,the gas that is emitted is
because plants breathe in carbondioxide and breathe out oxygen which animals and human breathe in if there is no carbondioxide there will be no plants ,no animalsand no humans which means no life on earth.
Air/gas animals and humans breathe in, and a little bit of nitrogen is included in the air it has just breathed in.
they breathe in the same way as daytime animals
we breathe out a gas called carbon dioxide
