Which of the following best explains why animals in the chaparral biome are not especially vulnerable to drought?

• A. They have adapted to survive with limited water availability.
• B. Chaparral animals rely exclusively on surface water sources.
• C. Most animals in the chaparral migrate to aquatic habitats during dry seasons.
• D. The chaparral biome receives abundant rainfall year-round.

Answer: (A)

Verified step by step guidance

1. Understand the chaparral biome: The chaparral biome is characterized by hot, dry summers and mild, wet winters. It is a region with limited water availability, especially during the summer months.
2. Analyze the adaptations of animals in the chaparral: Animals in this biome have evolved specific adaptations to survive in conditions of limited water. These adaptations may include behaviors like being nocturnal to avoid heat, physiological mechanisms to conserve water, or obtaining moisture from food.
3. Evaluate the incorrect options: The statement 'Chaparral animals rely exclusively on surface water sources' is incorrect because surface water is often scarce in this biome. Similarly, 'Most animals in the chaparral migrate to aquatic habitats during dry seasons' is not true, as most animals have adaptations to stay in the biome. Lastly, 'The chaparral biome receives abundant rainfall year-round' is incorrect because rainfall is seasonal and not abundant year-round.
4. Identify the correct explanation: The correct answer is that animals in the chaparral biome are not especially vulnerable to drought because they have adapted to survive with limited water availability. These adaptations are key to their survival in this environment.
5. Summarize the reasoning: By understanding the environmental conditions of the chaparral biome and the adaptations of its animals, it becomes clear that their ability to survive with limited water is the primary reason they are not especially vulnerable to drought.
