Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks which insect acquires distasteful chemicals to deter its predator birds.

2. **Recall Relevant Information**: The Monarch butterfly is known for its bright coloration, which makes it easily recognizable. However, this bright coloration can also make it a target for predators like birds.

3. **Understand the Adaptation**: To protect themselves from predators, Monarch butterflies have developed adaptations. They become distasteful and even poisonous to birds.

4. **Mechanism of Acquiring Distasteful Chemicals**: The Monarch butterfly acquires these distasteful chemicals during its caterpillar stage. Specifically, they feed on milkweed, which contains toxic compounds.

5. **Conclusion**: As a result of feeding on milkweed, the chemicals are stored in their bodies, making them unpalatable to birds. This adaptation helps them avoid predation.
