Which of the following organisms breeds only once in lifetime ?

Options

A. Bamboo
B. Oysters
C. Pelagic fishes
D. Birds

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which organism breeds only once in its lifetime. This means we need to identify organisms that have a single reproductive event before they die.

2. **Analyzing the Options**:
- **Option A: Bamboo**: Bamboo species are known to flower and reproduce only once in their lifetime, typically after a long period of growth (50 to 100 years). After flowering, they die.
- **Option B: Oyster**: Oysters breed annually, typically once a year, so they do not fit the criteria of breeding only once in a lifetime.
- **Option C: Pelagic Fishes**: Pelagic fishes are seasonal breeders, meaning they breed multiple times during specific seasons, not just once in their lifetime.
- **Option D: Birds**: Birds also breed once a year, which means they reproduce multiple times throughout their lives.

3. **Identifying the Correct Answer**: From the analysis, only the bamboo fits the criteria of breeding only once in its lifetime.

4. **Conclusion**: The correct answer is **Option A: Bamboo**.
