Here's why:
* Altitude and Climate: High mountains, even near the equator, experience significantly lower temperatures due to the decrease in atmospheric pressure. This creates a climate similar to polar regions.
* Low Temperatures: The alpine tundra is characterized by freezing temperatures for much of the year, with a short growing season.
* Low Precipitation: While the equator is known for high rainfall, mountains often block rain clouds, resulting in lower precipitation at higher elevations.
* Sparse Vegetation: The harsh conditions of the alpine tundra support only a limited amount of vegetation, primarily low-growing grasses, lichens, and small shrubs.
* Permafrost: In some cases, the ground may be permanently frozen (permafrost), further limiting plant growth.
While the specific plants and animals may vary depending on the mountain range, the general characteristics of an alpine tundra biome hold true.
