As climate changes because of global warming, plant species' ranges in the northern hemisphere may move northward. The trees that are most likely to avoid extinction in such an environment are those that ________.
A) have seeds that are easily dispersed by wind or animals
B) have thin seed coats
C) produce well-provisioned seeds
D) have seeds that become viable only after a forest fire
E) disperse many seeds in close proximity to the parent tree

Trees with seeds that are easily dispersed by wind or animals would have an advantage in adapting to shifting ranges caused by global warming. They would have a better chance of colonizing new areas quickly and surviving in the changing environment. Thin seed coats and well-provisioned seeds may also be advantageous, but the ability to disperse seeds is likely to be the most important factor in avoiding extinction. Seeds that become viable only after a forest fire or those that disperse many seeds in close proximity to the parent tree may not be beneficial in a changing climate.
