In one or two sentences, explain how the chemical equation for cellular respiration shows that plants cycle matter. Include the numbers of molecules and atoms involved to support your explanation.

Question

This is for Connexus, 7th Grade Science class.

Answer 1

The chemical equation for cellular respiration in plants shows that matter is cycled because it starts with glucose (C6H12O6) and six oxygen molecules (O2) and ends with six carbon dioxide molecules (CO2) and six water molecules (H2O), indicating that matter has been transformed but not lost or gained.
