• A. The chaparral experiences colder winters than the desert.
• B. The desert is characterized by frequent wildfires, while the chaparral is not.
• C. The chaparral receives more annual rainfall than the desert.
• D. The desert has a higher density of shrubs and small trees than the chaparral.

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the characteristics of the chaparral biome. The chaparral is a biome characterized by hot, dry summers and mild, wet winters. It typically has a mix of shrubs and small trees, and it experiences periodic wildfires. Importantly, it receives more annual rainfall compared to deserts, which is a key distinguishing factor.
2. Step 2: Understand the characteristics of the desert biome. Deserts are defined by their extremely low annual rainfall, making them the driest biome. They have sparse vegetation, which is adapted to conserve water, and they experience extreme temperature fluctuations between day and night.
3. Step 3: Compare the rainfall patterns of the two biomes. The chaparral receives more annual rainfall than the desert, which is a critical ecological difference. This additional rainfall supports a higher density of vegetation in the chaparral compared to the desert.
4. Step 4: Address the incorrect options. The statement that the chaparral experiences colder winters than the desert is misleading because deserts can also experience cold winters, especially in temperate deserts. The claim that deserts have a higher density of shrubs and small trees than the chaparral is incorrect, as deserts generally have sparse vegetation. Additionally, the chaparral is prone to wildfires, so the statement about wildfires being unique to deserts is also incorrect.
5. Step 5: Conclude that the correct answer is based on the difference in annual rainfall. The chaparral receives more annual rainfall than the desert, which supports its unique vegetation and ecological characteristics.
