Answer:
Photosynthesis demostrates the law of conservation of matter which states that atoms cannot be created or destroyed, the atoms can only be rearranged into the new molecules and ions. Photosyntesys is aided by enzymes, special proiteins, which can neither break chemical bons or form bonds in molecules.
Step-by-step explanation:
The amount of carbon-dioxide atoms released by respirations are exactly equal to the atoms of these materials contained in the oxygen and carbon coverted. In this way repiration has conserved the mass or material and in this way followed the law of conservation of mass.
