Cellular respiration will affect the oxygen levels by decreasing it.
CELLULAR RESPIRATION:
- Cellular respiration is the process by which living organisms obtain energy (ATP) by breaking down food molecules in their cells.
- Cellular respiration can either occur aerobically (with oxygen) or anaerobically (without oxygen). Aerobic cellular respiration uses oxygen to break down glucose molecules to form carbon dioxide and water as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O
- Based on the equation above, oxygen is a reactant meaning that it is used up during the cellular respiration process. Therefore, oxygen levels will decrease due to cellular respiration.

The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity
Temperature, humidity, and pressure are basically the same all through an air mass.
