Final answer:
Coniferous trees in the coniferous forest biome have adaptations such as needle-shaped leaves and a thick waxy coating to reduce water loss.
Step-by-step explanation:
Coniferous trees, such as pines, spruce, and fir, are the dominant plants in the coniferous forest biome due to their adaptations to the long and cold winters. These trees have needle-shaped leaves that retain their shape throughout the year, allowing them to photosynthesize earlier in the spring than deciduous trees. They also have woody trunks and a thick coating of waxy cuticle on their leaves, which helps reduce water loss in the dry conditions of the boreal forest.
