What are the producers of the tundra?
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.
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.
- Arctic cod eat krill and other aquatic invertebrates. Ringed seal eat arctic cod, as well as other fish. Euphausiids are pelagic crustaceans that feed on phytoplankton. They are important food to fish and to bowhead whales in the Arctic.
- Harp seals have a varied diet of fish such as capelin, polar and Arctic cod, herring, sculpin, Greenland halibut, redfish, and plaice. They also consume crustaceans such as amphipods, euphausids (krill), and decapods (shrimps and prawns).
- The open ocean is the world's "plankton pasture," home to the tiny drifting plants and animals that power enormous food webs. Copepods are the single most important group of animal plankton. Small fish feed on them and are in turn eaten by bigger fish, sea birds, seals and whales.
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.
- 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. Walruses may occasionally prey on fishes such as polar cod.
- Their main food is the Arctic willow (Salix arctica). They eat all parts of the plant. Their feeding can be destructive: they will break off sizable twigs and even dig up roots. The flowers of purple saxifrage (Saxifraga oppositifolia) are a favourite food in late spring and early summer.
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.

- Other Tundra Penguins. Two other penguin species can be found in tundra-like regions near Antarctica. Rockhopper penguins also live in tundra-like regions. However, they are found more frequently on southern Atlantic Ocean islands outside of the Antarctic polar front.
- When it looks like there is nothing to eat on the winter tundra, caribou will scrape the snow away with their wide feet or antlers and eat lichens, dried sedges and small shrubs. In the summer they the will eat leaves of willows, sedges, flowering tundra plants, and mushrooms.
