Answer:

Question no1: Polar bears inhabit arctic sea ice, water, islands, and continental coastlines. Polar bears hunt seals in the leads, using sea ice as a platform. ... Polynyas are areas of water, surrounded by ice, that remain open throughout the year due to winds, upwellings, and tidal currents.
