Diapause is stage of suspended development in lakes and ponds. Find out the season in which it occurs

Options

A. summer
B. winter
C. autumn
D. spring

Answer

**Step-by-Step Solution:**

1. **Understanding Diapause**: Diapause is defined as a stage of suspended development that occurs in certain organisms, particularly in response to unfavorable environmental conditions. This stage allows organisms to survive extreme conditions by pausing their growth and development.

2. **Identifying the Context**: The question specifically mentions lakes and ponds, where certain organisms like zooplankton may enter diapause to cope with environmental stresses.

3. **Analyzing Seasonal Conditions**: Organisms typically enter diapause during periods when environmental conditions are harsh. In the context of lakes and ponds, these conditions are often associated with extreme temperatures.

4. **Considering the Seasons**:
- **Summer**: Generally associated with warmer temperatures, which may not necessitate diapause.
- **Winter**: Characterized by cold temperatures, which can be stressful for aquatic organisms, leading them to enter diapause.
- **Autumn**: Transitional season, but not typically associated with the need for diapause.
- **Spring**: Usually a time of warming and growth, not a period for entering diapause.

5. **Conclusion**: Based on the analysis, it is clear that diapause occurs during the winter season when temperatures drop significantly, making it difficult for organisms to maintain their physiological processes.

**Final Answer**: The season in which diapause occurs is **B. Winter**.
