Polar Bears Research Paper

1156 Words5 Pages

Adaptation is the key to an organism’s survival. It is the only way that organisms can advance with the ever changing environment. According to Charles Darwin’s theory of evolution by natural selection, the organisms that obtain inheritable traits which permit them to adapt better to their habitat are more likely to survive, reproduction and pass these traits to their offsprings. Thanks to dedicated biological researchers, veterinarians and well-advanced technology, we now have incredible new insights into the life of the polar bears. Through remarkable structural and physiological adaptations, polar bears are the most successful organisms living under the extreme conditions of the Arctic Circle. The polar bear (Ursus Martimus) is a flesh-eating …show more content…

The nostrils are closed when the great mammal is under water to prevent internal drowning. As well as this, the hollow hairs (guard hairs) acts as a wetsuit. The blubber (fatty layer) keeps the bear warm as it moves through the freezing cold water.Polar bears are strong and fast swimmers and can obtain a swimming speed of approximately 10 kilometers per hour. This is a useful adaptation that helps them speedily escape when hunted by …show more content…

This implies that they cannot survive without the ice. The dependence of the large mammals on the frozen floating homes, especially for the rapid access of ringed seals, indicates their survival and breeding probabilities are based on the sea ice conditions. Due to their remarkable degree of specific adaptations to life on the frozen Arctic ocean, the bears are very successful. As a result of this, the polar bears are more vulnerable to the effect of climate change.(Fitzgerald, Kevin T (2013). Apart from the sea ice, the polar bears have very few alternatives left when the ice melts and when their access to the ringed seal prey disappears with their habitat. The charismatic arctic hunters cannot adjust and sustain themselves on another food source. If the devastating process of climate change continues, there wouldn’t be a thin sheet of ice left for these extraordinary animals to survive

    Some animals live and stay in the tundra while others migrate to another location. Animals that live and stay in the tundra include some birds like the ptarmigan and some mammals like the musk ox, arctic hare, and arctic fox (Woodward).It’s incredibly easy to destroy the tundra because of the lack of variations in the number of plants and animals. If something happens to the permafrost or if a species becomes extinct, the whole ecosystem may collapse. All species in the tundra are significant because the food chains there are very simple. A food chain can consist of an arctic fox eating a lemming, which devoured plants in the tundra, like mosses.
