The correct Answer is:
To determine the maximum amount of organic matter produced on Earth per year by photosynthesis, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Process of Photosynthesis**: - Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, producing organic matter (glucose) from carbon dioxide and water. 2. **Identify the Key Components**: - The main components involved in photosynthesis are: - Carbon dioxide (from the atmosphere) - Water (from the soil) - Sunlight (provides the energy needed for the process) 3. **Recognize the Types of Reactions**: - Photosynthesis consists of two main types of reactions: - **Light Reactions**: These are light-dependent reactions that convert solar energy into chemical energy (ATP and NADPH). - **Dark Reactions**: Also known as light-independent reactions, these use the energy produced in light reactions to synthesize glucose from carbon dioxide. 4. **Estimate the Annual Production of Organic Matter**: - The total amount of organic matter produced through photosynthesis globally is estimated to be around **2 x 10^11 tons** per year. This includes contributions from all photosynthetic organisms, including plants, algae, and certain bacteria. 5. **Conclusion**: - Therefore, the maximum amount of organic matter produced on Earth per year by photosynthesis is approximately **2 x 10^11 tons**. ### Final Answer: The maximum amount of organic matter that can be produced on Earth per year by photosynthesis is approximately **2 x 10^11 tons**. ---
