What elements are the main contituents of living organism?
the main constituents of living organisms is carbon with first position then oxygen with second hydrogen with third and nitrogen with fourth, the carbon is the most abundant portion in living organism and nitrogen least quantity. The free nitrogen quantity in atmosphere is considerably more.
What does respiration remove from 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.
In an oxygen enriched atmosphere some possible sources of elevated oxygen levels include?
leaking oxygen cylinders and liquid oxygen systems in the immediate area
The highest percentage in the atmosphere is of?
The highest percentage in the Earth's atmosphere is nitrogen, at 78%. Then oxygen(21%) and CO2, 0.9%.
Why did the earth's atmosphere change after it was first formed?
The earths atmosphere has significantly altered over the years. The process of the earth's atmosphere was recognized and evolved 2.7 billion years ago, forming the nitrogen-oxygen atmosphere that exists today. This change enabled the formation and beginning of the ozone layer (which along with magnetic fields) block solar radiation.
Which organism release oxygen into the atmosphere?
bird
What organism contributed the most to the shift between an oxygen-free atmosphere to an oxygenated-atmosphere?
The 'photosynthtics'
What added oxygen to earths early atmosphere?
Photosynthesis by plants
What element upon which most modern organism depend was missing from earth's early atmosphere?
Oxygen
What organism is given credit for helping change the gases in your atmosphere to oxygen?
Probably ancient cyanobacteria.
What added oxygen to earth atmosphere as they made food there?
The biggest contributer was and is algae.
Which organism gets its carbon from carbon dioxide?
Green plants take carbon dioxide from the atmosphere, and using energy from the sun separate the carbon from the oxygen. They release the oxygen to the atmosphere, and use the carbon.
What are three ways oxygen gas is removed from the atmosphere and use?
Animals respire. Plants respire. Fire uses oxygen. Rusting uses oxygen. Oxygen is removed from the atmosphere by 1. respiration 2. combustion and 3. gradual oxidation process at normal temperature and pressure. It is added to the atmosphere by photosynthesis of green plants.
What are the three main reservoirs of the oxygen cycle?
atmosphere biosphere and water cycle. ~ orliving organism | living organisms | organism | organism death | organismsocean | the ocean | the oceans | oceansrocks | rock
What happens to the atmosphere during cellular respiration?
oxygen is added to the atmosphere when plants take in carbon dioxide during cellular respiration
What chemical release to atmosphere when dead organism burned?
Carbon dioxide is released into the atmosphere.
An organism was added to a test tube containing water which was then sealed and placed in sunlight The test tube showed what type of organism was added an increase in oxygen over a period of time?
Green alga
