VI. Habitat Adaptation
Siberian Huskies have learned to adapt to their cold environment. They had thick double coat that allow them to live and thrive in subzero temps; a small, thickly-furred, erect ears which retain their body heat; two almond shaped eyes that protects the eyeball from wind chill and ice debris (the shape is an important factor); moderate-length muzzle which allows enough space to warm the arctic air breathed in before it reaches the lungs; and an efficient, hardy digestive system that allows the dogs to live and work on very little food (since food was a often scarce commodity among the nomadic hunting tribes that developed the breed).
These physical adaptations help the Siberian Huskies to survive the freezing temperature in the Arctic.
Metabolism is a term that is used to describe all chemical reactions involved in maintaining the living state of the cells and the organism (such as the Siberian husky). It is closely linked to nutrition and the availability of nutrients. The enzyme-catalyzed reactions allow organisms to grow and reproduce, maintain their structures, and respond to their environments. The word metabolism can also refer to all chemical reactions that occur in living organisms, including digestion and the transport of substances into and between different cells.
Siberian Huskies, unlike other breeds of similar size, have a highly efficient metabolism evolved from centuries of living in harsh arctic conditions.
Siberian Huskies do not need so much food due to the lack of food resources on their habitat. However, Sled-dogs need more food for the energy they need to fulfill their job. Moreover, overfeeding might result to obesity that would cause so many problems.
Siberian Huskies also need to be independent. If it had relied on its owners for food and direction, it would have died. These people took care of themselves first and the dogs second. Siberians often had to find their own...
