1. Why are the shallow roots of the raindeer moss adapted for life on the tundra?

2. why do forests not occur in the grassland?

1. One of the arctic willow's abilities is to produce a pesticide for itself to keep predators away. The plant adapted to the permafrost by growing shallow roots, not long roots, to keep from freezing itself over. Also, it grows close to the ground, to get out of the way of the wind.

2. In many natural areas that are considered grasslands, the reason trees do not grow is because the native wildlife kills the trees ... Another factor is that the grass can be quite tall in grasslands and saplings die because they don't get enough sun.
