It allows the tree to keep most of its leaves year round
What are two reasons that few large plants grow beneath the trees of a conifer forest
The ground beneath conifers is often covered in thick layers of needles. Also very little light reaches the ground.
Why do tropical rain forests have more biological diversity than other places on earth
Rain forests have more different kinds of plants and animals than any other land biome.
