The productivity and distribution of plants mainly depend on

Options

A. soil
B. temperature
C. water
D. light

Answer

**Step-by-Step Solution:**

1. **Understanding Productivity and Distribution**:
- Productivity refers to the rate at which biomass (organic matter) is produced in a given area over a specific time.
- Distribution refers to how plants are spread out or located in different environments.

2. **Factors Affecting Plant Productivity**:
- While soil type can influence plant growth, it is not the primary factor affecting productivity.
- Productivity is more closely related to the specific conditions of the environment, such as temperature and light.

3. **Role of Temperature**:
- Temperature has a significant impact on both the productivity and distribution of plants.
- Each plant species has an optimal temperature range for growth, which affects where they can thrive.

4. **Geographical Influence**:
- The equatorial region receives ample sunlight and has a warm climate (around 22-23 degrees Celsius), making it highly suitable for plant growth.
- Tropical regions also provide favorable conditions for plant distribution due to their climate.

5. **Conclusion**:
- Among various environmental factors, temperature stands out as a critical determinant for both the productivity and distribution of plants.
- Therefore, the correct answer to the question is that the productivity and distribution of plants mainly depend on temperature.

**Final Answer**: The productivity and distribution of plants mainly depend on temperature.
