Why is the arctic tundra classified as a biome?
Here's a good definition of biome:
"Biomes are defined as 'the world's major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment'" (Campbell).

The unique climate and vegetation qualifies the arctic tundra as a biome. Check the site linked above for a lot of information about the arctic biome.

The arctic tundra is classified as a biome because it is a distinct ecological community characterized by specific climate conditions and vegetation.
To understand why the arctic tundra is classified as a biome, we can refer to the definition of biomes. According to Campbell's definition, biomes are the major communities in the world classified based on the predominant vegetation and the adaptations of organisms to that particular environment. This means that a biome is characterized by its unique combination of climate and plant life.
In the case of the arctic tundra, it has a cold, harsh climate with long, freezing winters and short, cool summers. The average temperature is below freezing for most of the year. The arctic tundra also experiences strong winds and low precipitation, which mainly falls as snow.
The vegetation in the arctic tundra is mainly consists of low-growing plants such as mosses, lichens, and dwarf shrubs. These plants have adaptations to survive in the extreme cold and short growing season. The tundra is also known for the permafrost, which is a layer of permanently frozen ground that limits the growth of larger plants.
The combination of these unique climate conditions and specific vegetation types makes the arctic tundra a distinct ecological community. Therefore, it is classified as a biome.
