Tundra Food Chain | How The Tundra Food Chain Works?

Arctic Tundra food chain is very different from that of other food chains. The Arctic is a wilderness where all living organisms are in direct competition for the scarce resources available. Competition here is very severe, and it is for this reason why the population numbers are lower than those found in the temperate zones.

The food chain in the Arctic Tundra consists of predators such as owls, foxes, wolves, and polar bears at the top of the chain. Predators hunt herbivores, plant eating animals, such as caribou, lemmings, and hares. A few carnivores prey upon smaller predators. Beside this base food chain there are also many microorganisms which live on almost every surface for example in mosses and lichens to be found all over the tundra.

The food chain in the Arctic tundra consists of the following: predators, such as owls, foxes, wolves, and polar bears; herbivores, plants eating animals such as caribou, lemmings, and hares; and decomposers like bacteria.

In the Arctic Tundra there are several types of food chains. Some food chains are short, while others are longer. The plants and animals follow a circle from being eaten by one type of animal to eventually becoming food for another type of animal.

The life of an Arctic Tundra animal is defined by a constant struggle between the need to find food and avoid becoming someone else’s dinner. This eternal chain reaction is structured into a simple and very natural food web: plants, herbivores, carnivores, scavengers.

These predators eat herbivores because the Arctic tundra is such an unforgiving environment that a predator on its own can’t afford any weak links in its food chain. The Arctic tundra is very cold, covered mostly with snow and ice, and it doesn’t get much sunlight during the long winter months. This makes it hard for animals to find the nutrients they need to survive.

The Arctic Tundra is located in the Northern Hemisphere and encompasses a very large portion of Alaska, Canada, Greenland, and Russia. It is one of the coldest and harshest environments on Earth. It starts at the treeline and continues towards the south pole. The main vegetation that grows in the tundra has long roots in order to reach water under the frozen ground.
