Answer: (B)

Verified step by step guidance

1. Understand the role of producers in an ecosystem: Producers, such as plants, algae, and some bacteria, are organisms that can make their own food using light, water, carbon dioxide, or other chemicals.
2. Learn about photosynthesis: Photosynthesis is the process by which producers convert light energy into chemical energy stored in glucose. This process primarily occurs in the chloroplasts of plant cells.
3. Identify the key components of photosynthesis: The main components involved in photosynthesis are sunlight, water (H₂O), and carbon dioxide (CO₂). These are transformed into glucose (C₆H₁₂O₆) and oxygen (O₂).
4. Explore the light-dependent reactions: These reactions occur in the thylakoid membranes of the chloroplasts where sunlight is absorbed by chlorophyll, exciting electrons and splitting water molecules to release oxygen.
5. Examine the light-independent reactions (Calvin Cycle): In the stroma of the chloroplasts, ATP and NADPH produced in the light-dependent reactions are used to convert carbon dioxide into glucose, completing the process of photosynthesis.
