Transcript of The Artic Tundra Ecosystem

The Arctic Tundra Decomposers Arctic Scavengers Adaptations in the Tundra Natural Disaster Bacteria- There is tons of Mesophilic bacteria that is responsible for breaking down dead organisms.

Fungi- apart from bacteria, they are the most important decomposers in this biome. They are important because they break down tough debris

Actonomycets- Dirts " Earthy" smell is caused by actonomycets. They are the best for tough plant tissues like bark, paper, and stems. * Rabbits have color changing fur that changes color, to match their surroundings. It's white in the winter and brown in the summer.

* Animals might have thick fur or feathers to keep warm in the winter.

* A lot of animals gain a layer of fat in the winter. This also helps them keep warm. Global Warming: Causing the snow to melt and it causes animals to loose their homes, food will also become scarce and animals will die out. Arctic Wolf- They have strong scavenging abilities. It stalks Polar bear kill. It scares the smaller scavengers away.

Arctic Fox- The Arctic fox prays on seabirds, rodents etc. A large percentage of their food comes from scavenging.

Glaucous Gulls- They are a type of seabird that lives on the coast of the tundra. They eat dead fish and dead birds. Interdependence Lemmings eat Tundra plants, owls and foxes eat Lemmings. Arctic wolves eat the snowy owl, while red foxes eat Arctic wolves. Last, wolves eat red foxes. All these animals rely on each other for food. Producers Arctic moss- Arctic moss is one of the main producers in the Arctic Tundra's.

Arctic moss grows in the bottom of lakes in the Tundra. They have tiny leaves that grow only on one thick cell. It is the longest living Tundra producer ever recorded. It is one of the few plants in the tundra and it adapts to the cold climate. They have tiny leaves mostly on one thick cell.

Arctic willow- the arctic willow likes cold climates and also likes dry,cold, and open out places. It grows shallow roots and small hairs to survive in cold weather. It can reach a height of 15-20 cm tall.It grows in many different shapes from the climate.

Bear berry- The bear berry is a low growing evergreen. It has blackberry's on it's leaves. Their leaves are also curled backwards.They covered in very thick bark. It is a very useful plant. The fruit of the bear berry can be cooked with other food and many more. it can reach the height of 2-8'' Arctic Tundra Consumers Polar Bear- polar bears paws help them from slipping on the ice. They eat seals and many other animals. before they catch their prey they stalk them. One of the ways they hunt is by swimming under the ice. In the fall polar bears make dens for shelter. Males can grow up to ten/10 feet tall.

Moose- Did you know there are 6/six different species of moose. Male moose have enormous antlers. moose renew antlers once every year. Female moose don't have antlers. Moose can weigh from 600-1580 pounds. The moose can live up to 16 years. To be exact 10-16 years.

Arctic hare- The Arctic hare is brown in the summer and white in the winter. The arctic hare lives in unusual habitats to survive. Unlike many rabbits Arctic hares have very short ears. The Arctic hare can weigh about 9-12 pounds. Human affects on a ecosystem Humans affect the Arctic Tundra by polluting the air with carbon dioxide and many other bad things. Humans also affect the Arctic Tundra by hunting animals. The climate of the Tundra is getting warmer from humans using bad chemicals to make products. This is causing the Arctic Tundra to melt.
