Food Preferences And Resources. 1  Walruses prefer molluscs - mainly bivalves such as clams. They also eat many other kinds of benthic invertebrates including worms, gastropods, cephalopods, crustaceans, sea cucumbers, and other soft-bodied animals. 2  Walruses may eat the carcasses of young seals when food is scarce.
Weasels eat small animals, and raccoons eat animals, fishes, frogs, and fruit. Owls eat mice and chipmunks. Large secondary consumers, such as wolves, bears, and cougars, are the only ones who can bring down deer or elk. The larger carnivores may also eat smaller ones sometimes. There are other animals in this food web, such as foxes, beavers, black birds, and porcupines. Because the plants do so well, animals flourish too.
