the oxygen level decreases
The oxygen and carbon dioxide level is about the same as one would find out of the desert.
The level of oxygen decreases on high mountains because it is slightly havier than air.
In high tides areas, the water level is higher the average sea level. In areas between high tides, low tides from. In low tide areas, the water level is lower than average sea level.
The oxygen level remains about the same, but the density of the air is reduced.
because plants make oxygen with the help of sunlight and sunlight is present between 6 am to 6pm. so the oxygen level is high.

Oh yes. The troposphere is the lowest level of the atmosphere, the level that we live and breathe in, and it does have lots of oxygen in it, until you get to very high altitudes.
Low level of carbon- dioxide and more level of oxygen.
Bright red due to the high oxygen level.
They're all at sea level.
primarily because high latitude areas have "thin air" that is low oxygen concentration. as a result of this little oxygen that the body receives in high latitude areas, rbcs are produced in much greater amount to compensate for the decreasing oxygen carrying capacity of the blood. but if you ask me, it really does not help because what's the use of producing many rbcs if the body receives little oxygen? --thoughtfulobserver The increase in a person's RBC count in high altitudes is to compensate for the lower oxygen level in the air being breathed in. By increasing the number of RBC's (and hemoglobin by default) you are increasing your body's ability to take in as much oxygen as possible at one time. This allows for greater oxygen consumption due to the increased RBC's in comparison to the oxygen consumption with the normal RBC count.
