The lower the percentage of oxygen air contains, the more frequent a breath must be taken in order to maintain the blood oxygen level at an acceptable level.
respiration
It turns in into oxygen
plants do it by photosynthesis. And animals do it by respiration
No, Cellular Respiration returns carbon dioxide back into the atmosphere: Photosynthesis: Carbon Dioxide + Water -> Light Energy -> Sugar + Oxygen Cellular Respiration: Sugar + Oxygen -> C.R. -> Carbon Dioxide + Water
The amount of oxygen increased greatly
by oxygen in the atmosphere
The environment is what you live in. Part of the environment is the atmosphere and this contains Oxygen. In respiration you breath in the atmosphere and get the Oxygen you need from it.
oxygen
Oxygen can enter the atmosphere during celluar respiration, because if it enters photosynthesis, how about the other organisms?
No, it must be more. Remember respiration by animals plus the storage in the atmosphere. Plus random oxidation.
Celluar respiration affects global warming by putting Co2 into the atmosphere and having us breathe it out for them to transimt. But if there is more Co2 into the atmosphere, plants are getting overloaded and they are dying from overdose of O2.
oxygen is added to the atmosphere when plants take in carbon dioxide during cellular respiration
The essential gas is oxygen...
Oxygen is being renewed constantly by the process of photosyntesis which absorbs carbon dioxide and converts it into oxygen. The rate of photosyntesis is higher than the amount of respiration, so the amount of organisms will not make oxygen dissapear.
It released into the atmosphere, if it isn't immeadiately used in respiration.
