Food chain begins with

Options

A. respiration
B. photosynthesis
C. decomposition
D. decay

Answer

**Step-by-Step Solution:**

1. **Understanding the Food Chain**: A food chain represents the flow of energy and nutrients from one organism to another in an ecosystem. It typically starts with producers, which are organisms that can produce their own food.

2. **Identifying Producers**: In most ecosystems, the primary producers are plants. They are capable of converting sunlight into chemical energy through a process known as photosynthesis.

3. **Photosynthesis Process**: During photosynthesis, plants take in carbon dioxide from the air and water from the soil. They use sunlight to convert these raw materials into glucose, a type of sugar that serves as food for the plant.

4. **Conclusion**: Since the food chain begins with producers that create their own food, we conclude that the food chain begins with the process of photosynthesis carried out by plants.

5. **Final Answer**: The food chain begins with photosynthesis.
