What r some adaptions that help animals who live in the Alpine biome survive​
neonofarm [45]

The animals that live in the Alpine biome have to have special adaptations to survive in it as this is a biome with very harsh conditions for big portion of the year. The temperatures are very low, the winds are strong, winter lasts for half a year or more, and there's lot of snow. All this has made the animals to develop certain traits to help them survive. Some of those adaptations are:

- thicker and longer fur for better isolation form the outside conditions

- wider paws with denser and tougher skin, helping them to move easier in the snow and avoid frostbite

- larger lungs and nostrils for easier breathing in the high altitudes

- stockier bodies so that heat can be preserved easier

- the ears and tails are small and rounded in order to avoid frost bite

- big portion of them are able to hibernate for several months

This gene flow creates a new species that is different from previous population of organisms
