Which statement best describes how photosynthesis follows the law of conservation of mass?
leva [86]

Answer:

O The number of oxygen atoms in the reactants used by this process equals the total number of oxygen atoms in the products.

Explanation:

The statement that best describes how photosynthesis follows the law of conservation of mass is that the number of oxygen atoms in the reactants used by this process is equal to the total number of oxygen atoms in the products.

 The equation of photosynthesis reaction is given as:

        6CO₂    +     6H₂O    →    C₆ H₁₂ O₆ +  6O₂

According to the law of conservation of mass, matter is neither created nor destroyed during the course of a chemical reaction.

By the virtue of this, the number of oxygen atom on both sides of the expression must be the same. Also, the number of carbon and hydrogen atoms must also be the same.
