Final answer:
The evergreen forests, specifically the boreal forest, are dominated by evergreen coniferous trees such as pines, spruce, and fir. These trees retain their needle-shaped leaves year-round and have adaptations that allow them to thrive in cold and nutrient-poor environments. This gives them a competitive advantage over deciduous trees in the boreal forest.
Step-by-step explanation:
The evergreen forests, specifically the boreal forest, are dominated by cold-tolerant cone-bearing plants known as evergreen coniferous trees. These include pines, spruce, and fir, which retain their needle-shaped leaves year-round. The ability of evergreen trees to photosynthesize earlier in the spring and their adaptation to acidic soils with little available nitrogen give them a competitive advantage over deciduous trees in this biome.
Evergreen forests predominantly house cold-tolerant cone-bearing plants like pines, spruce, and fir, which retain their needle-shaped leaves year-round. These evergreen coniferous trees can photosynthesize earlier in the spring compared to deciduous trees and have a growth advantage in the acidic, nitrogen-poor soils of boreal forest regions.
In the evergreen forests, one predominantly finds cold-tolerant cone-bearing plants known as evergreen coniferous trees. This category includes trees like pines, spruce, and fir, which have the unique feature of retaining their needle-shaped leaves all year round. Due to this characteristic, these evergreen trees are able to photosynthesize earlier in the spring compared to deciduous trees, as they require less energy from the sun to warm their needle-like leaves.
This feature of evergreen trees proves advantageous, helping them to grow faster than deciduous trees in the same forest areas. Furthermore, the soils found in the boreal forest regions, where many evergreen forests are located, are usually acidic and scarce in nitrogen. Interestingly, leaves are a nitrogen-rich structure; hence, coniferous trees that retain their nitrogen-rich needles can have a competitive advantage over broad-leafed deciduous trees that need to produce a new set of nitrogen-rich structures each year.
