Which biome is characterized by cold winters and mild summers?

The taiga, also known as the boreal forest, is characterized by its cold winters and mild summers. This biome is primarily found in the northern regions of North America, Europe, and Asia. The taiga experiences significant temperature variations between the seasons, making the winters quite frigid, often with snowfall, while summers are relatively warmer, allowing for a growing season that supports a variety of coniferous trees such as spruce, fir, and pine.

This biome is also notable for its ecological importance, as it provides habitat for wildlife adapted to these seasonal changes. The cold climate in winter causes many species to enter a state of hibernation or migrate, while the milder summers promote growth and reproduction.

In contrast, other biomes listed in the question do not share this combination of characteristics. The tundra is even colder, with more severe winters and shorter growing seasons. Deserts are defined by their low precipitation and often extreme temperatures, leading to very different ecological conditions. Tropical rainforests, on the other hand, have warm temperatures year-round with high precipitation, completely differing from the seasonal climate found in the taiga.
