In which way are photosynthesis and cellular respiration different?

• Cellular respiration stores ATP, while photosynthesis releases ATP.
• Cellular respiration produces oxygen, while photosynthesis uses oxygen.
• Photosynthesis releases energy, while cellular respiration stores energy.
• Photosynthesis used carbon dioxide, while cellular respiration produces carbon dioxide.

What is the correct equation for cellular respiration?

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

How can energy from the sun be transferred to animals?

• The sun's energy is transformed into food by plants, animals eat plants as food so that they can transform that food into energy.

• Plants produced energy through photosynthesis, animals that eat that energy can produce food.

• Plants transformed energy of the sun into gases that animals can breath in to use as energy through respiration.

• Animals are able to use energy from the sun by eating the plants that provides energy for the animals.
