Plants:
* Berries: Grizzly bears love berries and will gorge themselves on them when they're in season. This includes blueberries, huckleberries, raspberries, and others.
* Roots and tubers: Grizzly bears dig for roots and tubers, especially in the spring and fall.
* Grasses and sedges: Grizzly bears graze on grasses and sedges, especially in the spring and early summer.
* Nuts and seeds: Grizzly bears will eat nuts and seeds when they're available, such as acorns, pine nuts, and hazelnuts.
Animals:
* Fish: Grizzly bears are excellent fishers and will eat salmon, trout, and other fish, especially during the spawning season.
* Mammals: Grizzly bears will prey on elk, deer, moose, caribou, and even bison when they get the chance. They also eat smaller mammals like rodents, squirrels, and rabbits.
* Carrion: Grizzly bears are opportunistic scavengers and will eat carrion, or dead animals.
* Insects: Grizzly bears will eat insects like ants, beetles, and grasshoppers.
The amount of food a grizzly bear needs to eat depends on its size, age, and activity level. However, a grizzly bear can eat an enormous amount of food in one sitting! They often store fat reserves during the summer to survive through the winter when food is scarce.
