How does the conservation of matter relate to the process of digestion?
IRISSAK [1]

Answer:

Explanation:

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

Explanation:

This law was given by french chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

For example:

When food is eaten it is digested by converting it into smaller particles. These smaller particles are than digest and gives the energy to our body. The energy which produced is just come from our food on this base we can say that mass neither created nor destroyed but it change one form to another, just like the form from food to energy.

Another example:

In given photosynthesis reaction:

6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂

there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
