Natural parthenogenesis occurs in

Options

A. honeybee
B. allinsects
C. protozoans
D. earthworm

Answer

### Step-by-Step Solution:

1. **Understanding Parthenogenesis**:
- Parthenogenesis is a form of asexual reproduction where an embryo develops from an unfertilized egg. This means that the egg does not require fertilization by sperm to develop into a new individual.

2. **Identifying the Organisms**:
- The question provides four options: honey bee, all insects, protozoans, and earthworm. We need to determine which of these organisms naturally exhibit parthenogenesis.

3. **Analyzing Each Option**:
- **Honey Bee**: In honey bees, the queen lays two types of eggs: fertilized and unfertilized. Fertilized eggs develop into worker bees, while unfertilized eggs develop into drones (male bees). This indicates that honey bees can reproduce through parthenogenesis.
- **All Insects**: While some insects can reproduce through parthenogenesis, not all do. Therefore, this option is too broad and not correct.
- **Protozoans**: Some protozoans can reproduce asexually, but parthenogenesis is not commonly associated with them.
- **Earthworm**: Earthworms typically reproduce sexually and do not exhibit parthenogenesis.

4. **Conclusion**:
- Based on the analysis, the correct answer is that natural parthenogenesis occurs in honey bees.

### Final Answer:
Natural parthenogenesis occurs in **honey bees**.
