Polar bear behavioral adaptation to survive in extreme temperatures?
Polar bears have had to become solitary creatures in order to survive in extreme temperatures. They must at times sleep when there is no food.
What are the CO2 levels doing to cause polar bear extinction?
Rising levels of CO2 and methane in the atmosphere are causing the temperatures to be warmer in the Arctic. Polar bears can only hunt when ice covers the ocean, but warmer temperatures melt the ice, which causes polar bears to starve.
How does rising temperatures affect polar bears?
Rising temperatures in the Arctic can lead to melting sea ice, which is crucial for polar bears to hunt seals, their main food source. As sea ice decreases, polar bears have to travel longer distances to find food, leading to increased energy expenditure and reduced chances of successful hunts. This can ultimately result in decreased body condition, reproduction rates, and survival rates for polar bears.
How will polar bears survive in the mountains?
They won't. They need to live and survive in the Arctic, not the mountains. Polar bears don't live in the mountains anyway.
Can baby polar bears survive alone?
No.
How do polar bears survive in winter?
Polar bears are busy chasing seals on Hudson Bay in the winter.
How are polar bears suffering?
Temperatures in the Arctic are rising at almost twice the rate of the rest of the world, and this is causing the early break-up of sea ice. Polar bears are dependent on the ice for their survival, which they use as a hunting platform, to secure mates and to travel.
How climate change could harm the biosphere?
Rising sea levels (due to ice melting & thermal expansion) - ecosystems destroyed,Rising temperatures- certain biomes will not survive (no water for plants & animals),Glaciers/ice-caps melting- polar bears forced to migrate & sea levels rise.
Why do polar bears eat?
Polar bears are very aggressive to other bears and can consider their young to be competition.
Which bears migrate?
Polar Bears migrate with their young every year. When temperatures warm up Polar Bears migrate to land to find food.
Do most polar bears cubs survive?
No not all polar bear cubs survive the harsh long winter.
Do polar bears often swim?
Yes, due to rising sea levels Polar bears often go for a quick paddle. The end
