What happened to increase oxygen levels in Earths atmosphere?
One would have to look at the grand scheme of things. If oxygen here increased, CO2 (carbon dioxide) would decrease, as well as Nitrogen. If that happened more plant would die off. Their oxygen giving would be cut off. More storms would occur, then something interesting would happen. Since we breath out carbon dioxide, we would put carbon dioxide back into the atmosphere! Oxygen would decrease, carbon dioxide increase, and nitrogen would increase due to lighting storms. Balance would come back in play, as long as mad scientists don't try to artificially pump back CO2 and nitrogen. Who knows? Perhaps plants would come back!
What compound does the oxygen come from?
Oxygen is an element or atom. Many molecules contain oxygen carbon dioxide and water being just two.
Where did the first oxygen molecule come from on Earth?
It is unsure were the first oxygen molecule came from came from, but my bet was that it was from the process "Outgassing" in which Water, Carbon Dioxide, and other fluids, were spewed out of volcanoes. The Carbon Dioxide was used by Cyanobacteria, or Stromatolites(sp?),in photosynthesis, thus producing oxygen.
What was Earths first atmosphere was created by?
The earths first atmosphere was created by the methane, carbon dioxide, sulphur oxides and water vapor that volcanoes were pumping out. Oxygen started to come in noticeable quantities once life had formed. Nitrogen is inert, so doesn't do anything.
What are the primary sources of sulfur oxides and nitrogen oxides?
sulfur oxides come primarily from coal burning in plants. Sulfur in coal reacts by combustion with oxygen to form sulfur dioxide. This reacts with ozone or a few other airborne chemicals to produce sulfur trioxide, which can react with rain and water vapor to create sulfuric acid. nitrogen oxides come primarily from high temperature devices, such as automobile and other transportation sources and coal burning plants. Nitrogen gas in the air reacts with oxygen in the air at high temperature to create nitrogen oxides, which can also react with ozone or other chemical agents to produce other nitrogen oxides which can react with rain and water vapor to create nitric acid. Also, carbon from any organic chemical can react with oxygen to produce carbon dioxide, which can react with rain and water vapor to create carbonic acid, but carbonic acid is a weak acid and is far less stable than sulfuric or nitric acid and can revert back to water and carbon dioxide easily.
Which gas do animals remove from the air?
The gas that is taken in by animals is oxygen. Animals absorb oxygen and exhale carbon dioxide. Plants take in carbon dioxide and let out oxygen.
Where does the carbon and oxygen and glucose ultimately come from?
the oxygen and carbon come from the Carbon Dioxide in the Dark Reactions of Photosynthesis. This didnt help
Where does most of the air huumans breath come from?
They come from plants. It is a cycle. (Carbon Dioxide and Oxygen Cycle) When you breathe out you realse Carbon Dioxide and the plants sucks it in and relase oxygen and that is what we breathe in.
Where do the carbon atoms come from to produce the certain sugar for photosynthesis?
From the animals around it breathing oxygen and converting it to carbon dioxide.
Where does carbon from photosynthesis come from?
From the animals around it breathing oxygen and converting it to carbon dioxide.
Where does the carbon from photosynthesis come from?
From the animals around it breathing oxygen and converting it to carbon dioxide.
How does the spiny lobster obtain oxygen and give off carbon dioxide?
When lobsters are underwater they breath in oxygen, when they come above water they breath out carbon dioxide.

What element does dioxide come from?
Dioxide means an oxygen molecule in a compound. Example CO2 is carbon dioxide, the O2 part is the dioxide.
The structures through which carbon dioxide and oxygen get in or come out of the plant are called what?
stomata
Where does mass come from?
The mass of a parcel of air is the result of the mass of the molecules of which it's composed ... you know, the nitrogen, oxygen, carbon dioxide, neon, argon, krypton, water, stuff like that.
Where does the carbon dioxde used by plants come from?
Humans inhale oxygen, and breath out carbon dioxide. It is like a cycle.
