Which biome is described as having evergreen coniferous forests and long winters?

• A. Taiga
• B. Tundra
• C. Grassland
• D. Desert

Answer: (B)

Biomes are shaped by climate and vegetation patterns. Evergreen coniferous forests with long winters point to the taiga, also known as the boreal forest. In this biome, winters are long and cold and summers are short, which favors trees like pines, spruces, and firs that keep their needles year-round to photosynthesize during the brief growing season. Soils tend to be acidic and nutrient-poor, and snow cover influences the ecosystem year after year.

Tundra, by contrast, is treeless and features permafrost, a very short growing season, and plants like mosses and lichens. Grasslands and deserts lack the characteristic evergreen conifer forests described, and have different moisture and temperature patterns.

Thus, the description most accurately matches the taiga.
