Photosynthetic yield maximum at the

Options

A. eqator region
B. polar region
C. both 1 and 2
D. arid region

Answer

**Step-by-Step Solution:**

1. **Understanding Photosynthesis**: Photosynthesis is the process by which plants convert light energy into chemical energy, producing food (glucose) and oxygen. The efficiency of this process can vary based on environmental conditions.

2. **Identifying Key Factors**: The primary factor affecting photosynthesis is sunlight. Plants require adequate sunlight to maximize their photosynthetic yield. Other factors include water availability, temperature, and carbon dioxide concentration.

3. **Analyzing the Given Regions**:
- **Equatorial Region**: This region receives direct sunlight throughout the year, making it ideal for photosynthesis. The consistent and high intensity of sunlight allows plants to achieve maximum photosynthetic yield.
- **Polar Region**: In contrast, polar regions receive very little sunlight, especially during winter months. The scarcity of sunlight limits the photosynthetic activity of plants in these areas.
- **Arid Region**: These regions have low water availability, which affects plant growth and photosynthesis. Plants in arid regions, such as cacti, have adapted to conserve water and may perform photosynthesis at night (C4 plants), but overall yield is still low.
- **Both 1 and 2**: This option suggests that both the equatorial and polar regions yield maximum photosynthesis, which is incorrect since the polar region has very limited sunlight.

4. **Conclusion**: Based on the analysis, the equatorial region is where photosynthetic yield is maximum due to optimal sunlight conditions.

**Final Answer**: The photosynthetic yield is maximum at the equatorial region.
