Answer 1

Answer: The AMOUNT of carbon-dioxide atoms released by respiration are EXACTLY EQUAL to the atoms of these materials contained in the oxygen and carbon converted. In this way respiration has conserved the mass or material and in this way followed the law of conservation of mass.

Answer 2

Definition: "Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products."

Simplified: Cellular respiration is used to take in food, then is used to create ATP. ATP is a chemical the cell uses for energy. This process is called aerobic respiration. The process uses oxygen, and has four stages known as Link reaction, glycolysis, the Krebs cycle, and the electron transport chain.

Aka: re-word the simple version a bit.
