photosynthesis and respiration

What is the process (equation) for photosynthesis?

• 6CO₂ + C₆H₁₂O₆ --> 6H₂O + 6O₂

• 6H₂O + 6CO₂ --> C₆H₁₂O₆ + 6O₂

• 6CO₂ + C₆H₁₂O₆ --> 6H₂O + Energy

• 6O₂ + C₆H₁₂O₆ --> 6CO₂ + 6H₂O

What is the relationship between the plant and the duck?

• "A" represents oxygen produced by the duck and "B" represents carbon dioxide produced by the plant

• "A" represents carbon dioxide produced by the plant and "B" represents oxygen produced by the duck

• "A" represents oxygen produced by the plant and "B" represents carbon dioxide produced by the Duck

• "A" represents the sunlight received by the plant and "B" represents the oxygen produced by the duck

Which describes the transfer in this image?

• Carbon Dioxide from the air becomes glucose in the plant. The deer ingest the glucose and it becomes carbon.

• Carbon Dioxide from the air becomes water in the plant. The deer ingest the water and it becomes oxygen.

• Oxygen from the air becomes carbon dioxide in the plant. The deer ingest the carbon dioxide and it becomes carbon.

• Water from the air becomes Oxygen in the plant. The deer ingest the Water and it becomes Oxygen.
