Question

the bodys input should be equal to the bodys output. choose the answer. the law of energy conservation. the principle of fluid dynamics. the theory of metabolic equilibrium. the law of mass balance

Explanation:

The law of mass balance states that the body's input should equal its output to maintain equilibrium. The law of energy conservation is about energy, fluid dynamics is about fluids in motion, and metabolic equilibrium is about metabolic - related balance. The given statement best aligns with the law of mass balance.

Answer:

The Law of Mass Balance
