An ecosystem is made up of animals, plants and bacteria as well as the physical and chemical environment they live in. Owing to its characteristic extreme conditions, the tundra is inhabited by a few plants and animals, each having a crucial role to play in its complex food web. This loss is multiplied over the length of a food chain: If 10% of available energy is transferred from primary producers to primary consumers (such as caterpillars) and 10% of that energy is transferred to secondary consumers (carnivores), then only 1% (10% of 10%) of net primary production is available to secondary consumers. Fish are eaten by seals (tertiary consumers), and seals are eaten by white sharks (quaternary consumers). In the Antarctic food chain krill are primary consumers and baleen whales, penguins, seals and many kinds of fish and other birds are secondary consumers when feeding on krill. Its predators are the Killer Whale and some large sharks. What is an ecosystem?

Producers in the arctic tundra include grass, moss plants, willow and reindeer lichen while consumers comprises of foxes, caribous, wolves, bears and birds like owls. Omnivores typically find their home in this category.
