oxygen-23%
nitrogen-71%
carbon dioxide-0.03
argon-0.9
Earth's atmosphere is approximately 79% nitrogen, 20% oxygen, and 1% "other gasses" such as carbon dioxide, hydrogen, neon, krypton, radon, and other gasses.
About 98.5% of the human body is composed.
Refer to the related link for a list indicating the percentages of different gases in the atmosphere.
They make up over 95% of a living organism.
For a human being the percentage is approx. 85 %.
nitrogen is 78% of the environment.
This percentage is approx. 7 %.
12.358% of Sulphur dioxide in the atmosphere.78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and other gases with very small percentage.
The Earth's atmosphere is approximately 79% Nitrogen, 20% Oxygen and 1% other gasses - including Argon, Neon and Carbon Dioxide.
78% of the Earth's atmosphere is Nitrogen. Another 21% is oxygen, and the final 1% are other gases found is small amounts such as carbon dioxide, helium and methane.
Nitrogen, Oxygen, Carbon Dioxide and Neon are the four main gases in order of percentage.
Plants started to grow on the earth, plants breath in carbon dioxide (which is why it decreased so much) and they breath out oxygen. That is why the percentage of oxygen has increased so much.
12.358% of Sulphur dioxide in the atmosphere.78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and other gases with very small percentage.
It is because plants take in carbon dioxide and breathe out Oxygen whereas, man and animals breathe in oxygen and breathe out carbon dioxide. This cycle of life maintaines a roughly same percentage of O2 and CO2 in the atmosphere.
Nitrogen,Oxygen,Carbon Dioxide And The rest of the percentage is other gases
The Earth's atmosphere is approximately 79% Nitrogen, 20% Oxygen and 1% other gasses - including Argon, Neon and Carbon Dioxide.
The balance of oxygen and carbon dioxide is maintained in the atmosphere by the oxygen released by plant during photosynthesis and carbon dioxide released by human ,animal's etc in the atmosphere
78% of the Earth's atmosphere is Nitrogen. Another 21% is oxygen, and the final 1% are other gases found is small amounts such as carbon dioxide, helium and methane.
Through oxygen cycle. Humans and animals take in oxygen and give out carbon dioxide. Plants take in carbon dioxide and give out oxygen. This ways the oxygen is circulated in the atmosphere.
Carbon dioxide is being released. As you breathe in you inhale fresh oxygen, but as you breathe out your body releases carbon dioxide.
Carbon dioxide is increasing in the atmosphere, and oxygen is decreasing.
Oxygen makes up roughly 20% of the atmosphere. Carbon Dioxide makes up 0.035% of the atmosphere.
Nitrogen, Oxygen, Carbon Dioxide and Neon are the four main gases in order of percentage.
Mars' atmosphere contains 0.13% oxygen. Over 95% of the atmosphere on Mars is carbon dioxide.
