Question

A population of wood beetles lives on a peninsula. A nising ocean turns the peninsula into a chain of islands The beetles are terrestrial and cannot cross the ocean.Which statement describes the most likely outcome for the beetles on the new islands?A. Some beetles in the population will be able to swim across, maintaining gene flow across the populations.B. The isolated beetle populations will not be able to survive the disruption and will go extinct.C. Geographic isolation will lead to the formation of new beetle species.D. Most beetle populations will die off, but one will remain.

Answer 1

The isolation of the wood beetles in a penincula will result to less survival of the species since the habitat have a limiting factor that will not be able to provide for its population when it increased in size. Since they do not have the ability to cross the ocean because they are terrestial, if food is no longer sufficient for their survival in their habitat, the population on the wood beetles will decrease.

Answer - Option B
