What is the main difference between the alpine tundra and the arctic tundra?
This is the world’s coldest biome. It receives only 6-10 inches of precipitation per year and has a permanently frozen layer of earth called permafrost. The soil is nutrient-poor with very little vegetation.
Organisms that live in the tundra biomes have developed unique adaptations that aid in their survival. The Labrador tea plant is a shrub that grows to be approximately five feet tall. Its leaves are used by human residents of the Arctic tundra to create both beverages and medicine. The leaves are harvested from each plant individually off the branches throughout the year. How has the Labrador tea plant adapted to enable its survival against the cold of the tundra biome?
The large size of the musk ox _______.
What type of vegetation is not frequently found in the tundra?
Which of the following animals has fur that changes color with the season?
Which of the following is an adaptation to permafrost?
Why is there limited vegetation in the tundra?
The tundra experiences little rainfall, which makes the soil devoid of nutrients. The soil is permafrost, or permanently frozen. Both of these factors make it difficult for plants to grow in the tundra.
Which of the following statements about the tundra is not true?a.The tundra has limited vegetation.b.There are two main categories of the tundra biome.c.Temperatures in the tundra can get below -20° F. d.The tundra biome does not support animal life.
The arctic tundra is located in the northern hemisphere. Please select the best answer from the choices provided
Why are plants and animals able to survive in the tundra?
Plants and animals have developed specific adaptations that allow them to survive the extreme climate of the tundra. These adaptations include thick fur, dense hair, retention of dead leaves, and feathered feet.
Mammals do not live in the tundra, because the climate is too extreme.
Tundra means “treeless land.”

The musk ox has a large body size and small appendages. How do these characteristics enable it to survive in the tundra?
The large body size and small appendages of the musk ox help minimize its heat loss. The smaller the surface area of an animal compared to its weight, the more slowly it loses heat. The musk ox has a large weight relative to its surface area.
How does the Alaska blackfish survive in waters with temperatures of 5ºF?
The Alaska blackfish survives in water with temperatures of 5ºF by producing chemicals that lower the freezing temperature of cellular fluids. This keeps the fluids of the fish from freezing, allowing it to survive.
Explain how the woolly lousewort has adapted to the cold climate of the tundra?
The woolly lousewort has dense hairs that surround its flowers. These hairs trap the heat from the sun and allow its temperature to be maintined, keeping the flower at a warm enough temperature for it to germinate its seeds.
