The Arctic cod is a small forage fish that is a very important part of the food web. It eats mostly zooplankton and lives water between -2 and 0°C due to a type of antifreeze in its blood. How does a warming climate and seas waters as well as ice melt impact the Arctic cod and the other organisms in the food web?
A) As the water temperatures warm, the plankton increases, the cod increases and all of the higher level consumers also increase.
B) As ice melts and temperatures increase, the polar bears decline so all other animal populations, including the Arctic cod, increase.
C) The Arctic cod lives in a very small temperature range. If it begins to die out, the food source for the next level of consumers will be reduced.
D) The Arctic cod will eventually adapt to the changing water temperatures. Since there is plenty of food for the cod, its population should remain stable.

Read the following scenario to answer the following question. over the past 60 years, many amphibian species have experienced significant population declines, and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. when most populations of a wide-ranging amphibian species are lost and the few remaining populations are widely separated, we expect to see that a. the founder effect becomes increasingly important b. microevolution no longer occurs c. gene flow between populations is reduced d. artificial selection becomes a greater factor in microevolution
