In response to global climate change, it is likely that some plant species will survive while others will go extinct. all of the following are explanations of this pattern except:
a. some plants are able to migrate more effectively than others and can move into areas with more favorable conditions for survival
b. co2 is toxic, so increasing levels of these gases will directly cause some plants to go extinct
c. temperatures may increase more rapidly than some species can adapt, which will lead to their extinction
d. plants differ in their abilities to respond physiologically to persistent environmental change, and only some will survive increased temperatures.
