Which statement about photosynthesis is correct?

• Plants get the energy they need for photosynthesis from water.
• Plants get the energy they need for photosynthesis from soil.
• Plants get the energy they need for photosynthesis from sunlight.
• Plants do not require energy to perform photosynthesis.

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 

Which of the following best describes photosynthesis?
