Only plants would, but then they would exhale O2 so then we'd have O2 again.
O2=Oxgen
Now wait, how would we end up with an Oxygen-less atmosphere? I'd imagine that the process of replacing the atmosphere with something that isn't Oxygen would result in genetic mutations preferring lifeforms which breathe other things.
Unless we're talking about having no atmosphere at all, in which case only the Glorious Robot People of the Democratic Republic People's Free Union of Socialist Robots (DRPFUSR) would survive.
If oxygen were to be removed from earth, all life forms that require oxygen to survive will die out leaving the earth as we know it baron. Oxygen is vital to our survival, without it we would die.
If there were no oxygen on Earth, most living organisms, including humans, would not be able to survive as oxygen is essential for respiration. Without oxygen, aerobic organisms would suffocate and eventually die. The atmosphere would likely become unbreathable, leading to widespread extinction of life.
No, because the atmosphere keeps in all the oxygen. Without the atmosphere the oxygen would escape.
If there were no oxygen on Earth, most living organisms, including humans, would not be able to survive. This is because oxygen is essential for cellular respiration, the process that generates energy for living organisms. Additionally, without oxygen, the ozone layer would also be unable to protect the Earth from harmful solar radiation.
No
Without oxygen, living organisms that depend on it for respiration would not survive. Chemical reactions that rely on oxygen, such as combustion, would not occur. The atmosphere would lack ozone, leading to increased exposure to harmful UV radiation.
Without oxygen, most living organisms, including humans, would not be able to survive. The process of respiration, which is essential for generating energy, relies on oxygen. Without it, there would be widespread death and extinction.
oxygen
No. We need plants which produce oxygen to survive. The oxygen in our atmosphere is entirely created by plants (originally phytoplankton in the oceans) so for us to survive on another planet there would have to be some sort of oxygen producing organisms. It's unlikely that a non-carbon based life would produce oxygen as oxygen is a by product of photosynthesis - turning carbon dioxide to carbon and oxygen. If the lifeform was not carbon based it would have no use for creating carbon. We'd also need the percentage of oxygen to be fairly close to that on Earth (around 20%) and the rest of the atmosphere to be composed of inert gasses (ideally nitrogen as on Earth). This would imply a balance between oxygen producing organisms and oxygen consuming organisms. We'd need there to be liquid surface water and some sort of plant like organisms which produce something we could eat (or to plant our own plants there to eat. The temperature would need to be fairly close to Earth, partly for there to be liquid surface water and partly just so we could survive - we can survive in a wide range of temperatures but not higher than about 40 degrees centigrade and not lower than about -20 degrees.
photosynthesis requires CO2 not oxygen so the plants would be fine and they would eventually replace the oxygen. Hope this helps :)
The oxygen and water we have with the multiple resources to eat and grow, and hunt.
