Tundra Ecosystem Adaptations and Characteristics

The tundra is the coldest biome, characterized by low temperatures, short growing seasons, and minimal precipitation, mostly as snow or ice. The soil contains permafrost, a permanently frozen layer. Plants in the tundra are adapted to absorb solar energy and grow quickly during the short growing season. They often grow close to the ground and use snow for insulation. Animals in the tundra have thick fur or feathers and blubber for insulation. Many animals migrate to the tundra only during milder conditions, and white fur or feathers provide camouflage against the snow.

What prevents trees from growing in the tundra?

• Abundant sunlight

• Very low temperatures and short growing season

• Long growing season

• High precipitation levels

What is permafrost?

• A type of plant found in the tundra

• A layer of soil that remains frozen year-round

• A type of animal adaptation

• A form of precipitation

How do tundra plants adapt to absorb more solar energy?

• By spreading their roots widely

• By producing more seeds

• By having dark-colored leaves

• By growing taller

Why do some tundra flowers follow the sun across the sky?

• To conserve water

• To attract pollinators

• To avoid predators

• To absorb warmth

What is the purpose of blubber in tundra animals?

• To help them swim faster

• To provide insulation against the cold

• To camouflage with the snow

• To store food

Why do many animals migrate to and from the tundra?

• To find more food

• To escape predators

• To breed in warmer areas

• Due to extremely cold winter conditions
