Which of the following observations demonstrates that living systems follow the law of conservation of mass?
A The total mass of a dead organism equals the total mass of matter released to the environment by decomposition.
B Most plants and animals begin their life cycle with a smaller mass and gain mass during development.
C The total mass of all organisms in an ecosystem remains the same over time.
D Living animals must consume food with a mass much greater than the mass of their body over their lifetime.

Respuesta :

The living system that followed the law of conservation of mass represents the total mass for the dead organism should be equivalent to the total mass of matter released.

What is the law of conservation of mass?

In the chemical reaction, the mass should not be developed not destroyed just like the carbon atom in coal should become carbon dioxide at the time when it should be burned. So, the observation that need to be represented should be that the total mass of the dead organism should be equivalent to the total mass of matter released with respect to the environment via decomposition.

Therefore, option a is correct.
