Tundra

Alana Hill and Trinity Balzer

Location

The Tundra is located in the most north o the northern hemisphere; a place called the arctic circle. The arctic circle spans from the top of Russia to the top of Canada. More specifically the Tundra is in the North Pole.

Weather

In the tundra it is very dry. There are short summers and long winters. The tundra is very cold and can reach -50 fahrenheit in the winter. During the summer the temperature barely goes past 50 fahrenheit. In the winter everything is frozen, and in the summer everything is soggy.

Adaptations

In the Tundra plants and animals have adapted to fit the cold and dry environment. Plants in the Tundra usually grow in groups, are adapted to be short, and have adapted to low light and colder temperatures. Plants and animals have both adapted to use minimal energy to stay fat and warm. Animals only breed when it’s warm, and in the winter they either hibernate or migrate. Animals typically change their diet throughout the year to match the changing weather.


Variations

In the Tundra there are several variations of foxes between grey, arctic, and red. Another variation is the variation of whales, Killer Whales and Beluga Whales. The variation of owls are, Snowy Owls and Long Eared. Different types of goose are the Bryant Geese, Canadian Geese, and Snow Geese.

How organisms uniquely adapted/varied due to their environment

In the Tundra plants adapted to the Tundra's unique colder temperatures and less amounts of sunlight. Wolves, oxen, and caribou have thicker fur so they can be warm in the Tundras cold winters. Arctic Wolf adapted to having white fur so that in can blend in with the snow so predators or prey are less likely to see the. Weasles adapted their shelter to an underground den for warmth.

Description of interdependency between organisms

Interdependency between the animals varies. The arctic wolf depends on the Musk Ox for food and the Snow Owl depends on mice for food. The main relationships between animals is predation and competition. Some relationships like commensalism can be seen with organisms and non-living things like moss and rocks.

Adding an Exotic Animal

If you add a snow tiger to the Tundra it would reek havoc on the ecosystem because it would eat many of the different food sources from each level and would result in little to none of a food source.

Taking Away a Native Spieces

If you took away cod, then the cod would not eat the krill, shrimp, and grasshoppers resulting in an overpopulation. With a loss of a food source everything that eats cod would be have less to eat which would cause an underpopulation and competition.
