Chemical
turning sunlight, water, and carbon dioxide in oxygen and ATP
We inhale oxygen and exhale carbon dioxide as a result of a change in our bodies. Answer - Chemical Change
because they need carbon dioxide for photosynthesis they are just like humans but they take in carbon dioxide and then change it to oxygen and release it in the air
In my own opinion and un-tested hypothesis.... that carbon oxygen cycle start to change when there is no more plants to give oxygen and get carbon dioxide and there is no animals and humans that inhale oxygen and give off or exhale carbon dioxide.
The equation is:2 CO2 ===========> 2 CO + O2
Oxygen concentration tends to decrease as carbon dioxide levels increase. This is due to the fact that high carbon dioxide levels can displace oxygen in the air, leading to lower oxygen concentrations. Therefore, there is an inverse relationship between oxygen and carbon dioxide concentrations in the atmosphere.
No. Carbon dioxide is a chemical compound of carbon and oxygen.
Oxygen in & carbon dioxide out. The change occurs within the cells and blood carries the gasses between the lungs and the cells.
Carbon dioxide is at high levels and oxygen at low levels in blood that is being pumped from the heart to the lungs.
Carbon dioxide is a compound consisting of carbon and oxygen.
Carbon is an element, but not carbon dioxide. Carbon dioxide is a compound of carbon and oxygen.
i don't completely under stand your question, but if you're asking why the amount of it in the air doesn't change, the answer is simple. we breathe in oxygen and let out carbon dioxide. while plants "breathe in" carbon dioxide and let out oxygen. oxygen is also made from chemical reactions from the ocean. but this is not enough to supply this much life with oxygen, and we still don't know where all the extra oxygen came from.
