Do any of anda know anything about bears? If anda do can anda help me?

I am an animal/bear expert and I will be honored to help anda answer your questions:
1. No, baby bears cannot surivie without their mother's care because if so, they could be eaten atau attacked oleh other bears atau even other binatang such as cougars and wolves. But without their mother's care, they will not be able to live without their mother's susu atau unless if the cubs are a few months of age, they may not be able to surive long enough without protection.
2. Grizzly Bears can eat wild berries, nuts, fish, and other binatang such as deer and elk.
3. When a beruang cub is found without its mother, it might either try to take care of itself oleh defeinding itself away from any other animal (including other bears) atau it may end up dying.
4. Bears attack humans because due to the fact that humans are attacking them and their homes. If humans will learn to accept a bear's privacy atau living, they will not attack. Sometimes, they may even terroize neighborhoods just for the cari of food.
5. Yes and no. If the cub is only a few years old and if it learned the tricks of how to defend itself from its mother, it will be able to protect itself from preadtors. But if the cub didn't learn the skills however, it might not be protected. (But sometimes, cubs will climb on trees to escape from an enemie's clutches)

I hope my jawaban help anda a lot. :)
