Exploring the Tundra Biome: Characteristics, Flora, and Fauna

The tundra biome, located primarily in the northern hemisphere, is characterized by its treeless landscape, extremely low temperatures averaging -34°C in winter, and a brief growing season of just 50-60 days in the Arctic, extending up to 180 days in alpine regions. This biome experiences minimal precipitation and has very low nutrient levels. Flora includes alpine tussock grasses, dwarf trees, and various lichens, while fauna comprises mammals such as caribou and polar bears, numerous bird species, and a variety of insects. Discover the unique features that define tundra ecosystems.
