Too much logging in the oyamel fir forests could lead to the eastern monarch butterfly going extinct because <u>the entire population of the species spends winter in oyamel fir forests.</u>
<u>Why it is the correct option:</u>
a. The oyamel fir forests serve as the winter home for the eastern monarch butterflies. The entire population of monarch butterflies moves to oyamel fir forests in Mexico during winters to protect themselves from the freezing cold temperatures of their natural, breeding habitat. So, too much logging of the oyamel fir trees will destroy the winter habitat of these butterflies, and hence will lead to the decline in their population.
<u>Why the other options are incorrect:</u>
b. the butterflies breed in the oyamel fir trees is an incorrect option because the monarch butterflies breed in their natural habitats in the US.
c. the winters are too cold in oyamel is an incorrect option because these butterflies move to oyamel forests to protect themselves from cold.
d. the butterflies feed on the oyamel fir trees is an incorrect option because the monarch butterflies feed on milkweed.
