Explanation:

Part 1 Question 1

To determine which organisms perform photosynthesis, we recall: Plants (with chloroplasts) do photosynthesis. Algae (like green algae) are photosynthetic. Fungi are heterotrophic (no photosynthesis). Animals are heterotrophic. All bacteria don’t photosynthesize, but some bacteria (e.g., cyanobacteria) do.

Photosynthesis uses light energy, carbon dioxide, and water to produce glucose (chemical energy) and oxygen. The overall purpose is to convert light energy into chemical energy (stored in glucose) to fuel the organism and release oxygen.

Photosynthesis inputs: Light energy (from the sun), Carbon Dioxide (CO₂, from the air), Water (H₂O, from the soil). Outputs: Glucose (C₆H₁₂O₆, chemical energy) and Oxygen (O₂, released into the air). The diagram’s sun - related box is light energy. The left box (near sun) could be light energy. The bottom left (entering the tree) is water. Bottom right (entering) is carbon dioxide. The middle box (tree) is the process (photosynthesis in chloroplasts). The right box (exiting) is oxygen, and glucose is produced (stored in the tree).

Answer:

• plants (checked)
• Algae (checked)
• Fungi (unchecked)
• all bacteria (unchecked)
• Animals (unchecked)
• some bacteria (checked)
