The process of photosynthesis can be represented by the chemical formula

• A) C6H12O6 + 6O2 → 6CO2 + 6H2O + energy

• B) C6H12O6 + 6H20 → 6CO2 + 6H2O

• C) 6CO2 +6H2O + energy → C6H12O6 + 6O2

• D) 6CO₂ + H₂O → C₆H₁₂O₆ + 6O₂

The process of cellular respiration can be represented by the chemical formula

• C6H12O6 + O2 → CO2 + H2O + energy

• C6H12O6 + H20 → CO2 + H2O

• CO2 + H2O + Light → C6H12O6 + O2

• CO2 + H2O → C6H12O6 + O2

Photosynthesis and cellular respiration are two biological processes that make a significant contribution to the carbon cycle. Evaluate these statements. Select ALL of those that demonstrate the role of photosynthesis in the cycling of matter into and out of organisms (#3).

• Photosynthesis uses carbon dioxide from the atmosphere.

• Photosynthesis releases carbon dioxide into the atmosphere.

• Photosynthesis returns carbon to the ground as plants die and decompose.

• Photosynthesis stores energy in the form of glucose (C6H12O6).

• Photosynthesis provides glucose (C6H12O6) to herbivores in the environment.
