Which of the following correctly distinguishes between the alpine and taiga biomes?
A
The alpine biome is found at high elevations above the tree line, while the taiga biome is a vast coniferous forest found at high northern latitudes.
B
Both the alpine and taiga biomes are dominated by broadleaf deciduous trees.
C
The alpine biome receives more precipitation than the taiga biome throughout the year.
D
The taiga biome experiences warmer temperatures year-round compared to the alpine biome.
Verified step by step guidance1
Step 1: Understand the key characteristics of the alpine biome. The alpine biome is typically found at high elevations above the tree line, where conditions are too harsh for trees to grow. It is characterized by cold temperatures, strong winds, and low oxygen levels. Vegetation is usually limited to grasses, shrubs, and small plants adapted to these conditions.
Step 2: Understand the key characteristics of the taiga biome. The taiga biome, also known as the boreal forest, is a vast coniferous forest found at high northern latitudes. It is characterized by long, cold winters and short, mild summers. The dominant vegetation includes coniferous trees such as spruce, fir, and pine.
Step 3: Compare the vegetation in both biomes. The alpine biome is not dominated by broadleaf deciduous trees, as the harsh conditions prevent their growth. In contrast, the taiga biome is dominated by coniferous trees, not broadleaf deciduous trees. This eliminates the option that both biomes are dominated by broadleaf deciduous trees.
Step 4: Analyze precipitation patterns. The alpine biome generally receives less precipitation than the taiga biome, as it is often located in regions with dry conditions. This eliminates the option that the alpine biome receives more precipitation than the taiga biome.
Step 5: Compare temperature ranges. The taiga biome experiences warmer temperatures year-round compared to the alpine biome, as the alpine biome is located at higher elevations where temperatures are colder. This supports the distinction that the alpine biome is found at high elevations above the tree line, while the taiga biome is a vast coniferous forest at high northern latitudes.
