Tundra Biome

Tundra

The tundra is the coldest biome. It has short summers that last 6 to 10 weeks when the sun shines almost 24/7. And even with constant sunlight and heat it never gets any hotter than 50 degrees Fahrenheit. In the winter, it's always dark and is -30 to 20 degrees Fahrenheit.

It's treeless and takes up one-tenth of the earth. The tundra is located near the North pole. The abiotic factors are wind, water, ice, and snow. The physical features are ice and snow. The soil is permafrost and its important because the tundra will began to decay if it thaws.

The tundra helps regulate the temperate of the Earth. Without it, places that currently support life may be lifeless.

Climate and Weather

The tundra is always icy and cold. The summers are short and last about 6-10 weeks. During the summer, the sun is out almost 24/7. The highest temperature can get to 50 degrees Fahrenheit and in the winter the lowest can get to -30 degrees. The average percipatation is 6-10 inches.

How humans have impacted the Tundra

One thing that is affecting the tundra is global warming. Global warming is the earth getting warmer because the sun's heat is getting trapped by extra carbon dioxide that is being released into the air because of the use of use of fossil fules. This is causing the ice and snow to melt, resulting in plant and animal This is causing the ice and snow to melt, resulting in plant and animal habitat loss. We can't bring back the cold and freeze the tundra again, but we can do thing to stop the tundra from melting.

Food Webs

All food webs start with the sun. In this food web, the producers are lichens, grasses, and arctic wildflower. They make their food using the sun's energy. The primary consumers in this food web are the musk ox, caribou, arctic hare, and lemming. They eat the producers. The secondary consumers are the polar bears and hawks. They eat the primary consumers. The decomposers are mushrooms, although they might get eaten by primary consumers like caribou. Wolves are tertiary consumers because the eat owls, which are secondary consumers. Wolves hunt in packs and compete with polar bears for food.
