Question

The laws of conservation say that mass and energy can be neither created nor destroyed, although they may be transformed.

Write a scientific explanation describing how the processes of photosynthesis, cellular respiration, and the carbon cycle follow these laws.

Answer 1

The carbon atom changes from a solid structure to a gas but its mass does not change. Similarly, the law of conservation of energy states that the amount of energy is neither created nor destroyed.

Answer 2

The law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.
