Answer: Option C) The oxygen atoms diffuse through the atmosphere and are inhaled by animals.
Step-by-step explanation:
The equation for photosynthesis is shown below:
6CO2 + 6H2O --> C6H12O6 + 6O2
The oxygen gas released during
photosynthesis is inhaled by animals. So, plants gives off oxygen as by-product, while humans gives off carbon dioxide as by-product.
Thus, oxygen and carbon dioxide is balanced and recycled in nature
