Which of the following statements is true about the taiga biome, but not the alpine biome?

• A. It is dominated by extensive coniferous forests such as spruce, fir, and pine.
• B. It experiences permafrost throughout the year.
• C. It has low biodiversity due to extreme cold and wind exposure.
• D. It is found at high elevations above the tree line.

Answer: (A)

Verified step by step guidance

1. Understand the characteristics of the taiga biome: The taiga biome, also known as the boreal forest, is characterized by extensive coniferous forests such as spruce, fir, and pine. It is typically found in northern latitudes and has cold temperatures with seasonal variations.
2. Understand the characteristics of the alpine biome: The alpine biome is found at high elevations above the tree line. It is characterized by extreme cold, wind exposure, and low biodiversity due to harsh environmental conditions.
3. Compare the two biomes: The taiga biome is dominated by coniferous forests, which is not a feature of the alpine biome. The alpine biome is above the tree line, meaning trees do not grow there, unlike the taiga biome.
4. Evaluate the other options: Permafrost is a feature of tundra biomes, not specifically the taiga or alpine biomes. Both the taiga and alpine biomes experience low biodiversity due to extreme conditions, so this is not unique to the taiga.
5. Conclude the distinguishing feature: The presence of extensive coniferous forests is a unique characteristic of the taiga biome and does not apply to the alpine biome.
