The distribution patterns of terrestrial biomes can be determined based almost entirely on which of the following factors?

• A. Soil mineral content
• B. Temperature and precipitation
• C. Wind speed and direction
• D. Animal migration patterns

Answer: (B)

Verified step by step guidance

1. Understand the concept of terrestrial biomes: Terrestrial biomes are large ecological areas on Earth's surface, defined primarily by vegetation type, which is influenced by environmental factors such as climate.
2. Recognize the key factors influencing biome distribution: Temperature and precipitation are the primary factors that determine the types of vegetation and organisms that can thrive in a particular biome. These factors shape the climate of the region.
3. Analyze why soil mineral content is not the primary factor: While soil quality can influence plant growth within a biome, it does not determine the overall distribution of biomes. Biomes are defined by broader climatic conditions rather than localized soil characteristics.
4. Evaluate why wind speed and direction are not the primary factors: Wind can affect weather patterns and seed dispersal, but it does not directly determine the large-scale distribution of biomes. Biome distribution is more closely tied to temperature and precipitation patterns.
5. Consider why animal migration patterns are not the primary factor: Animal migration is a response to environmental conditions within biomes, but it does not dictate the distribution of biomes themselves. Biomes are defined by abiotic factors like climate rather than biotic factors like animal behavior.
