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.
