Question

Polar bears hunt for ringed seals by waiting on them to emerge from breathing holes in the ice
What abiotic change may decrease the bears ability to hunt
Increased seal population
Increased ice cover
Increased temperature
Increased competition

Answer 1

The abiotic change that may decrease the bears' ability to hunt is **increased temperature**. Rising temperatures can lead to the melting of sea ice, which is critical habitat for polar bears. With less ice available, polar bears have a harder time accessing the breathing holes of ringed seals, making hunting more difficult.
