Question

Explanation:

1. Taiga is a biome also known as boreal forest. It is found in the northern - hemisphere continents. North America and Eurasia have large areas of taiga.
2. In the tundra, the upper soil is muddy in summer because the top layer of soil thaws while the permafrost below remains frozen. This prevents water from draining downwards, resulting in a muddy upper - soil layer.
