What do bears prefer to eat most

only the basic bears

Explanation:

Black bears are very opportunistic eaters. Most of their diet consists of grasses, roots, berries, and insects. They will also eat fish and mammals—including carrion—and easily develop a taste for human foods and garbage.

Alaskan brown bears are opportunistic eaters and will eat almost anything. Their diet consists of berries, flowers, grasses, herbs, and roots. They get their protein from beavers, deer, caribou, salmon, carcasses, and other small mammals.

Polar bears feed mainly on ringed and bearded seals. ... When other food is unavailable, polar bears will eat just about any animal they can get, including reindeer, small rodents, seabirds, waterfowl, fish, eggs, vegetation (including kelp), berries, and human garbage.

A panda's daily diet consists almost entirely of the leaves, stems and shoots of various bamboo species. Bamboo contains very little nutritional value so pandas must eat 12-38kg every day to meet their energy needs.
