Arctic tundra Tundra Ecosystems projects Biology Diagrams Reindeer reside in the tundra, which is the plain between the polar ice cap and the timberline. See more arctic animal pictures. . Ralph Lee Hopkins/Getty Images . It's surprising that the thousands of wild reindeer roaming the barren tundra of North America, Europe and Asia have never united to overthrow Santa's famous eiยญght. While Comet and crew live it up at the North Pole, dining on Snowy owls, wolverines, and Arctic wolves-the tertiary consumers in tundra food chain-feed on Arctic hares and reindeer to fulfill their energy requirement. Even though a major chunk of the diet of this gray wolf subspecies consists of reindeer, it is also known to feed on small mammals and even on snowy owls at times.
The different groups of organisms in a basic Tundra food chain are: Producers. They eat plants such as lemmings, musk ox, reindeer, squirrels, voles, and arctic hares. Mosquitoes, flies, moths, grasshoppers, arctic bumble bees, other insects, and birds such as ravens, falcons, and gulls are also found in this trophic level. Reindeer grazing directly impacts the composition of the Arctic tundra by selectively feeding on shrubs, curbing their expansion, and allowing herbaceous species to flourish. thereby reinforcing the intricate web of the Arctic food chain. Additionally, reindeer serve as a primary food source for key predators such as wolves and bears. This
Tundra Food Chain: Examples and Diagram Biology Diagrams
Lower-Middle of the Arctic Tundra Food Chain. The lower-middle Arctic food chain consists of moose, caribou, reindeer, Arctic tern, and other birds, dalls sheep, muskox, snowshoe hare, lemmings, beavers, squirrels, voles, shrews, wood frogs, white fish, salmon, and other fish. If the lower middle tier didn't exist, the top and upper-mid of
Trees cannot grow here due to the cold, dry climate. Squirrels, lemmings, hares, reindeer and caribou are primary consumers that feed on plants. Arctic foxes, grizzly bears, wolves, and falcons are some of the animals that prey on the primary consumers. Arctic tundra ecosystems also include marine life such as polar bears, seals, salmon, gulls The example below shows the energy flow in a basic food chain in The Tundra. This food chain is part of a more complex food web involving producers and consumers (herbivores, carnivores, and omnivores). Producers here include grasses, lichens, and caribou moss. Herbivores that eat these plants include the musk ox, arctic hare, and lemmings.
Tundra Food Chain: Understanding the Complex Ecosystem of the Arctic Web Biology Diagrams
The food chain is the backbone of this ecosystem, and it starts with the primary producers. Understanding how each organism in the food chain is connected is essential to understanding the complex tundra biome. 2. What is a Food Chain? A food chain is a series of organisms that are interdependent on each other for food.
