Question

explain why the numbers of caribou and wolf in the Arctic rise and falls in cycles????Give a short answer ​

Answer 1

$\huge \mathcal \red{Answer:-}$

• Caribou try to protect themselves from wolves by sleeping on frozen lakes in the winter, where they can see wolves before they get too close. A healthy caribou can usually outrun a wolf across the hard-packed snow on a frozen lake, or across the tundra in the summer.

Answer 2

Explanation:

Arctic wolves tend to be smaller than timber or tundra wolves because of harsher conditions and sparse food population. Adult males average about 35 kg in weight and 1.5 meters in length from nose to tip of the tail, while adult females average 30 kg and 1.4 meters. Primarily, the wolves in the Arctic are white or cream and the coat is thick, composed of long, coarse outer hair and shorter, soft fur underneath. (From our previous descriptions of other animals, ranging from sled dogs to muskox, it is clear that many different species have evolved a similar layering of fur for an extremely cold environment.) Wolves mate in late March and the females produce litters of four to seven pups in late May or early June. In a den that the mother has dug herself, or in many cases refurbished, the pups are born blind and deaf. Pups remain with their pack for at least the first year to survive. While many wolves leave the pack over their second summer or winter — usually because of rivalry for mates — some remain with their pack for several years.
