Here's why:
* Biome Definition: A biome is a large-scale community of organisms that share similar climate, vegetation, and adaptations.
* Mountains and Polar Regions: While they have unique characteristics, mountains and polar regions meet the criteria for biomes:
* Climate: They have distinct climates that influence the types of plants and animals that can thrive there.
* Vegetation: Mountainous areas have distinct altitudinal zones with different vegetation, and polar regions support unique flora like tundra.
* Adaptations: Both environments have organisms with specific adaptations to survive the harsh conditions.
Perhaps you're thinking of something else?
Could you clarify what you mean by "not considered terrestrial biomes?" Are you asking:
* Are there different classifications within mountains or polar regions?
* Are there other biomes within mountains and polar regions?
If you can provide more information, I can give you a more specific answer!
