Good Morning! The biome closest to the polar caps is called "Tundra". This biome is recognized for its extremely low temperature (up to 10 ° C), filled with marshes (formed by the melting ice), lichens, mosses and small shrubs. The animals that inhabit these regions (mainly Canada and Alaska), seek their food in the summer. Among them we have: reindeer, foxes, wolves and hares. Hugs!
