Grizzly bears don't affect the life of polar bears. They are just the same type of species living in a different area . They have no effect on each other.
Grizzly bears are the biggest predators in their environment. Even wolves and mountain lions can't kill grizzly bears because the Bears are well armed with their size, strength, claws, and teeth. However, grizzly bears can be a threat to each other; in particular, males often try to kill cubs so that their mothers will be ready to breed sooner.
== == No they never run into each other because polar bears do not live in the forest.
yes they do the males fight each other over the female the female fights against other bears to defend their cubs or home food etc
Yes. Brown bears, like Grizzly Bears especially, often kill and eat adult or young black bears whenever they meet each other.
Black bears are not known to eat other species of bears, or to be cannibalistic in nature. Here is a detailed outline of their diet:"Black bears are omnivores whose diet includes plants, meat, and insects. Their diet typically consists of about 10-15% animal matter." --WikipediaFor more information, please see the related link below this answer:
Grizzly bears live in North America, and anacondas live in south america. They will never meet each other. Either way, an anaconda cannot eat a grizzly bear as the bear is too robust and big.
They mark their territory, either by marking a tree or leaving large prints in the ground. They actively avoid each other.
The scientific name of the grizzly bear is Ursus arctos horribilis, while the scientific name of the polar bear is Ursus maritimus. Both bears are in the Ursus genus which indicates that they share many common attributes.
Brown bears have no natural enemies except man. Cubs are sometimes killed by pumas and male bears, but healthy adults fear only man and each other.
The adult males will eat their young. Adult females sometimes adopt orphaned cubs. The adult females will keep adult males away from cubs. Adult males avoid each other. However, along the Pacific coastline when the salmon are running each year, the bears DO tolerate each other.
I believe that it is called a Plantigrade Gait, which means that the animal that is moving with this gait keeps the heel as well as all the toes on the ground when it walks. This bear walks quite slowly and deliberately compared with other mammals.
