Please use the following information to answer the question(s)below. In areas of permafrost,stands of black spruce are frequently observed in the landscape,whereas other tree species are noticeably absent.Often these stands are referred to as "drunken forests" because many of the black spruce are displaced from their normal vertical alignment. -What might be the adaptive significance of these unusual forests growing the way they do in this marginal habitat? A)Needles are adapted to withstand cold Arctic temperatures. B)Branches are adapted to absorb more CO₂ with this displaced alignment. C)Taproot formation is impossible,so trees developed shallow root beds and easily tilt. D)Trees are tilted so that snow won't break them or tip them over. E)Trees tip so that they do not compete with each other for sunlight.

In permafrost areas, the ground is too hard for trees to develop deep taproots. Instead, black spruce trees have shallow root systems that make them prone to tilting, which is why they are often seen in the "drunken" alignment. This adaptation allows them to survive in the challenging conditions of permafrost.
