Artic Tundra
by: Nakayla Pickens and Jordan Vega
Geographical Location
Arctic tundra is found across northern Alaska, Canada, and Siberia.
Climate
Tundras are among Earth's coldest, harshest biomes.Tundra ecosystems are treeless regions found in the Artic and on the tops of mountains, where the climate is cold and windy and rainfall is scant. Summer in the Tundra only last about 6 weeks. The warmest it gets here is 50 degrees
Average Rainfall
Yearly precipitation, including melting snow, is 15 to 25 cm (6 to 10 inches). Soil is formed slowly.
Artic Tundra Plants
food webs and food chains in the arctic tundra
A typical Arctic tundra food chain in Alaska begins with lichen, which is both an alga a producer and a fungus a decomposer living symbiotically. Lichen can live on bare rock in the tundra and slowly break it down to soil. A caribou, a primary consumer, eats the lichen and later dies. A brown or grizzly bear an omnivore stumbles upon the dead body and consumes it, becoming both a scavenger and secondary consumer.
Bearberry
Bearberry is a low growing evergreen. It has a stem that rises 2-8" off the ground and is covered in a thick bark and fine silky hairs.
diamond-leaf willow
The twigs on a willow are soft, slender, and they bend easily.A willow has thin branches. The leaves are narrow and grow alternately on the branch. Some leaves have serrated edges.There are many different species of willows in the world.They can grow to be 30 feet in height or just a few inches.
labrador tea
The Labrador tea plant grows to be 4 to 5 feet. It will grow up straight in the southern latitudes of the tundra, but in the colder northern latitudes it will creep over the ground forming a carpet. It has woolly branches with narrow 1 to 2 inch leaves which are smooth on the upper side, with rusty hairs underneath.
