Arctic tundra animals food web

The second most numerous large mammal in the world after man is the crab eater seal an archetypal antarctic animal. The antarctic food web is relatively simple compared to ecosystems in other parts of the world. The arctic seal is eaten by the polar bear and eats the atlantic salmon. When the spring thaw bursts forth a simple tundra food web quickly begins production. Food the arctic fox follows it. Plants are devoured by herbivores and carnivores eat the animals that have eaten the plants. The polar bear is in most risk. The tundra biome has three subtypes the arctic tundra in the northern hemisphere antarctic tundra in the southern hemisphere and the alpine tundra which occurs at high altitudes in various mountains across the world. Show students photos of arctic animals. There are fewer different species but greater numbers of individuals of each. Producers here include grasses lichens and caribou moss. While the arctic wolf is apex predator in the arctic tundra biome the snow leopard holds this distinction in the alpine tundra. These herbivores are then eaten by carnivores such as arctic foxes and brown bears. Start the food web at the sun start the ball of yarn there. Is where arctic foxes follow a polar bear to where it eats.

Show students what an arctic food web looks like two food web diagrams are included in the lesson materials. Help the students create the arctic food web. A food web in antarctica s tundra depends primarily on the ocean where tiny phytoplankton feed many organisms year round. The arctic tern eats the atlantic salmon which than eats the krill. Once the caribou is done hunting the arctic fox goes back to the hole and digs deeper and gets its food. The ermine also consumes the lemming. Assign an animal or organism to each or a group of students. Atop the food chain are tundra carnivores such as arctic foxes vulpes lagopus arctic wolves canis lupus snowy owls bubo scandiaca and polar bears ursus maritimus which move into the tundra during the summer when prey is plentiful and their usual hunting grounds on sea ice diminish. The arctic hare eats the arctic willow which is also eaten by the lemming. The animals that the polar bears eat are in great risk of dying out and so this will affect the polar bears at any extreme point. In this web the territorial consumer is the polar bear which is also found in the arctic tundra. The polar bear eats the atlantic salmon and so does the arctic seal. This food chain is part of a more complex food web involving producers and consumers herbivores carnivores and omnivores. The caribou digs a slightly deep hole in the snow covered ground in a quest to find food. Each of these have distinct food webs of their own.
