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.
