How do jack pines adapt to taiga?

Answer 1

Jack pines adapt to the taiga biome by having specialized needles that are shorter and waxy to reduce water loss in the cold and dry environment. They also have serotinous cones that require intense heat, like from a forest fire, to open and release seeds, allowing for successful regeneration after disturbances. Their shallow root systems help them access nutrients in the thin soil layer found in taiga regions. Overall, these adaptations enable jack pines to thrive in the harsh conditions of the taiga biome.
