Photosynthesis is performed by:

• Animals

• Plants

• Autotrophs

• Heterotrophs

These organisms CREATE food using light energy. Therefore, we refer to them as

• Producers

• Consumers

• Decomposers

• Heterotrophs

Balanced chemical equation of photosynthesis:

• 6CO₂ + 6H₂O --> C₆H₁₂O₆

• C₆H₁₂O₆ + 6O₂+ Light -> 6CO₂ + 6H₂O

• 3CO₂ + 4H₂O + Light -> C₆H₁₂O₆ + O₂

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

Photosynthesis occurs in 2 stages: 1 - ​ (a)   (including the electron transport chain) and 2 - ​ (b)   which is also called the ​ ​ (c)   Cycle

• Light Dependent
• Light Independent
• Calvin
• Respiration
• Citric Acid
