Poor bears hunt for wrenched seals by waiting for them to emerge from breathing holes in the ice, which a biotic change made decrease a pool bears ability to hunt increase ceiling population increased ice cover increased competition or increased temperatures.

Answer 1

The correct answer is "increased ice cover." When ice cover increases, it decreases the number of breathing holes available for seals to use. As a result, bears have a harder time hunting seals, causing them to have a smaller pool of prey to hunt from. This may result in poor hunting for bears and can have negative implications for their population.
