Which of the following is an adaptation that helps animals survive in the alpine biome?

• A. Gills for extracting oxygen from water
• B. Bright coloration to attract pollinators
• C. Large, flat leaves to maximize sunlight absorption
• D. Thick fur to insulate against cold temperatures

Answer: (D)

Verified step by step guidance

1. Understand the alpine biome: The alpine biome is characterized by cold temperatures, high altitudes, and limited vegetation. Animals living in this biome must adapt to survive harsh conditions, including cold temperatures and low oxygen levels.
2. Analyze the options provided: Evaluate each adaptation in the context of the alpine biome. For example, gills for extracting oxygen from water are suited for aquatic environments, not the alpine biome. Bright coloration to attract pollinators is more relevant to plants or animals in environments where pollination is a key survival strategy. Large, flat leaves are plant adaptations for maximizing sunlight absorption, not animal adaptations.
3. Focus on insulation against cold: Thick fur is a common adaptation in animals living in cold environments, including the alpine biome. It helps retain body heat and provides protection against freezing temperatures.
4. Relate thick fur to survival: Thick fur acts as an insulator by trapping warm air close to the animal's body, reducing heat loss. This adaptation is crucial for maintaining body temperature in the alpine biome's cold climate.
5. Conclude the correct adaptation: Based on the analysis, thick fur is the most relevant adaptation for animals to survive in the alpine biome, as it directly addresses the challenge of cold temperatures.
