Polar bears primarily prey on seals, particularly ringed and bearded seals, which they hunt on sea ice in the Arctic. They rely on platforms of ice to wait near seal breathing holes or to break through the ice to access seals beneath. Additionally, they may scavenge on carcasses of marine mammals or hunt other prey when seals are scarce. Their hunting grounds are typically in areas where sea ice is present, as it serves as a critical habitat for their hunting activities.
Why do polar bears have thick water-repellant fur?
Polar bears have thick water-repellant fur to insulate them against the frigid Arctic temperatures and to keep them dry while swimming or moving through icy waters. The fur consists of two layers: a dense undercoat for insulation and longer guard hairs that repel water and snow. This unique adaptation helps polar bears maintain their body heat and stay buoyant in their icy habitat, enhancing their survival in extreme conditions.
What features serve as reservoirs to temporarily store water in mountainous and polar regions?
In mountainous and polar regions, features such as glaciers, snowfields, and ice caps serve as reservoirs to temporarily store water. Glaciers accumulate snow and ice during colder months, gradually releasing meltwater during warmer periods, which feeds rivers and ecosystems. Snowfields act similarly, storing water as snow that melts in spring and summer. Additionally, permafrost in polar regions can temporarily hold water in a frozen state, impacting hydrology when it thaws.
What poses a great threat in the polar regions and why?
The greatest threats in the polar regions include climate change, which leads to rising temperatures, melting ice caps, and habitat loss for native species. Additionally, increased human activity, such as oil drilling and shipping routes, poses risks of pollution and potential oil spills. These changes disrupt the delicate ecosystems and can have cascading effects on global weather patterns and sea levels. Furthermore, the loss of ice habitat endangers species like polar bears and seals, which rely on ice for hunting and breeding.
