Explanation:
The boreal forest is a biome that is found in the Northern Hemisphere. It is located between the temperate forests and the tundra. These forests are dominated by coniferous trees.

The animals that live in these forests are the elk, moose, deer, wolverines, wolves, black bears, mink, foxes, lynx, among others. All these animals have special adaptations that enable them to live in this biome. They all have thick fur for most of the year, only shedding slightly during the summer.Their paws tend to winder and have goo isolation so that they can walk easily on the snow and avoid frostbite.

Answer:
Shifting cultivation is an agricultural system in which plots of land are cultivated temporarily, then abandoned while post-disturbance fallow vegetation is allowed to freely grow while the cultivator moves on to another plot. The period of cultivation is usually terminated when the soil shows signs of exhaustion or, more commonly, when the field is overrun by weeds. The length of time that a field is cultivated is usually shorter than the period over which the land is allowed to regenerate by lying fallow.
