Flura & Fauna

Bear berry: 

Bear Berries are autotrophic plants and are producers for animals such as the Polar Bear, and the Snowy owl.

 Polar bear:

The polar bear is a tertiary consumer and is an omnivore. It has no predators and it eats Bear berries, Musk oxen, Caribou, Walrus and the Harp Seal.

  

Arctic bumble bees:

The Arctic Bumble Bee is a primary consumer and a herbivore. It eats the nectar from the Arctic poppy. It also feeds off the Arctic Willow and The Diamond leafed willow. Its predators are small birds such as the Dunlin in the Arctic Alaskan Tundra.  

Arctic Poppy:

Arctic poppy is an autotrophic plant and is also a producer, the main predator which is not really a predator, in the arctic tundra: is the Arctic Bumble Bee.

Environmental importance

There are factors such as: global warming (the rising temperatures would cause the ice on the high peaks of the tundra to melt, this would cause a change to the landscape which eventually would affect the species living there), invasive species (that may affect the natural animals and plants life by affecting the food chain, for example the Red fox which was introduced by Europeans), air pollution (causing smog clouds to form which might contaminate reliable food sources, water sources and the oxygen within the Arctic Tundra) oil spills (caused by humans and threatens many wildlife species, possibly through water sources) as well as buildings and roads that projects heat to the surroundings causing organisms that live in the Arctic Tundra such as the Polar bear, have no use for its blubber and have to adapt to its new environment changing many things such as: the food chains and webs within the ecosystem, adaptions of many other species, etc. 

Climate

In the arctic tundra there are two seasons: winter and summer. In the summer, the sun is present almost 24 hours a day. This sun however, only warms the tundra up to a range of about 3°C to 12°C. In the winter the opposite light conditions are present. There are several weeks where the sun never rises. This causes the temperatures to drop to extremely cold levels. The average temperature of the tundra is around -28°C while extremes can dip to -70°C.

Characteristics

The Arctic tundra is a cold, vast, treeless area of low, swampy plains in the far north around the Arctic Ocean. It includes the northern lands of Europe (Lapland and Scandinavia), Asia (Siberia), and North America (Alaska and Canada), as well as most of Greenland. Another type of tundra is the alpine tundra, which is a biome that exists at the tops of high mountains.
