Final answer:
Photosynthesis models the law of conservation of matter by rearranging atoms without creating or destroying matter.
Step-by-step explanation:
Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. The chemical equation for photosynthesis is:
6CO2 + 6H2O + sunlight → C6H12O6 + 6O2
This equation models the law of conservation of matter because it shows that the number of each type of atom on both sides of the equation is the same. In other words, matter is neither created nor destroyed during photosynthesis, only rearranged.
