Earthworms undergo copulation for about

Options

A. One hour
B. Four to five minutes
C. Four hours
D. Six hours

Answer

**Step-by-Step Solution:**

1. **Understanding Earthworm Reproduction**: Earthworms are hermaphrodites, meaning each individual has both male and female reproductive organs. This allows them to engage in copulation with another earthworm.

2. **Duration of Copulation**: The copulation process in earthworms lasts for approximately 1 to 1.5 days. This is a significant duration compared to many other organisms.

3. **Cross-Fertilization**: During copulation, earthworms engage in cross-fertilization. This means that they exchange gametes (sperm) with each other rather than self-fertilizing.

4. **Positioning During Copulation**: During the copulation process, the two earthworms align in a juxtaposed position, which facilitates the exchange of reproductive material.

5. **Completion of Copulation**: After the exchange of gametes, the copulation process is considered complete. This intricate process is essential for the reproduction of earthworms.

6. **Conclusion**: Therefore, the correct answer to the question is that earthworms undergo copulation for about 1 to 1.5 days.
