Is the Arctic fox a secondary consumer?
A secondary consumer is an animal that eats primary consumers. They are all over the world but in the arctic there are arctic foxes, seals, penguins, and much more. Animals can be primary and secondary or secondary and tertiary consumers. For instance, birds can eat fish and seeds.
they eat plankton, copepods amphipods, euphaisids , arrow worm, shrimp, as well as arctic cod. Narwhals, beluga whales and ringed seals feed on these fish. the food that eats an arctic cod would decrease and the prey the cod would eat would increase.
- The arctic cod has a circumpolar distribution and occurs farther north than any other marine fish. Its vast distribution spans the Arctic seas off northern Russia, Alaska, Canada, and Greenland.
- Polar bears feed mainly on ringed and bearded seals. Depending upon their location, they also eat harp and hooded seals and scavenge on carcasses of beluga whales, walruses, narwhals, and bowhead whales. On occasion, polar bears kill beluga whales and young walruses.
- Atlantic cod was a top-tier predator, along with haddock, flounder and hake, feeding upon smaller prey, such as herring, capelin, shrimp, and snow crab. With the large predatory fish removed, their prey have had population explosions and have become the top predators, affecting the survival rates of cod eggs and fry.
Arctic tundra moss and lichen. "Lichens dominate the tundra as the major primary producer. Many lichens can be covered with ice for up to three years and still remain alive. Lichens are a symbiotic relationship between two organisms – an alga and a fungus.
- The tundra is located at the top of the world, near the North Pole. This enormous biome, extremely uniform in appearance, covers a fifth of the earth's surface. The most distinctive characteristic of tundra soil is its permafrost, a permanently frozen layer of ground.
- Caribou also eat the leaves of willow and birch as well as grasses and sedges will be on their menu.Caribou prefers eating lichen because it is very healthy. Musk-oxen live in the frozen Arctic and roam the tundra in search of the roots, mosses, and lichens that sustain them.
- The arctic willow is a food source for several arctic animals. Muskoxen, caribou, arctic hares, and lemmings all feed on the bark and twigs, while the buds are the main food source of the ptarmigan.
Adult cod are omnivorous carnivores, which means that they feed on any animal that they can engulf. Their menu includes bristle-worms, mussels, squids, crustaceans and fishes such as sand eel, Norway pout, capelin, sticklebacks, sprat and herring.
- Copepods and other invertebrates (animals without a backbone) feed on microscopic algae. Polar bears prefer to eat ringed and bearded seals, but will also eat arctic fox, walrus and beluga whales. Arctic cod eat krill and other aquatic invertebrates. Ringed seal eat arctic cod, as well as other fish.
- Food Preferences & Resources. Polar bears feed mainly on ringed and bearded seals. Depending upon their location, they also eat harp and hooded seals and scavenge on carcasses of beluga whales, walruses, narwhals, and bowhead whales. On occasion, polar bears kill beluga whales and young walruses.
- The sea ice algae are eaten by grazers such as zooplankton (either single-celled or multi-celled organisms that are not plants) for their own nutritional needs. In the Arctic food web, some whales have special teeth called baleen. These teeth let them feed on the zooplankton by filtering plankton-rich seawater.
