Question

1. how has global warming made it more difficult for polar bears to hunt the seals they feed on? a. the population of seals has declined. b. polar bears are forced to swim longer distances between ice - sheets. c. seals now have more places to hide. d. polar bears are now being hunted more by other predators.

Explanation:

Global warming causes sea - ice to melt. Polar bears rely on sea - ice platforms for hunting seals. With melting ice, the distance between ice sheets increases, forcing polar bears to swim longer distances, which is energy - consuming and makes hunting more difficult. There is no indication that seal population decline is directly due to global warming making it harder for polar bears to hunt in the context of this question. There is no evidence that seals have more hiding places or that polar bears are hunted more by other predators due to global warming.

Answer:

B. Polar bears are forced to swim longer distances between ice sheets.
