Multiple Choice

Which of the following is the correct equation for PHOTOSYNTHESIS?

• 6CO₂ + 6H₂O --> 6O₂ + C₆H₁₂O₆
• 6CO₂ + C₆H₁₂O₆ + 6H₂O --> O₂ 
• 6O₂ + 6H₂O --> 6CO₂ + C₆H₁₂O₆
• C₆H₁₂O₆ + 6O₂ ---> 6H₂O + 6CO₂

Multiple Choice

What are the products of cellular respiration?

• Energy (ATP), Water, and Carbon DIoxide.
• Water and Oxygen
• Oxygen and Carbon Dioxide
• Water and Energy (ATP)

Multiple Choice

What are the products of photosynthesis?

Multiple Choice

In which eukaryotic organelles does photosynthesis occur?

• mitochondria

• stomata

Multiple Choice

Only 10% of the energy is passed on from one trophic level to the next. 90% is lost as heat due to cellular respiration or waste.

• Tertiary Consumer
