Question

What are the characteristics of tundra?

Answer 1

Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation.
Characteristics of tundra include:

Extremely cold climate
1. Low biotic diversity
2. Simple vegetation structure
3. Limitation of drainage
4. Short season of growth and reproduction
5. Energy and nutrients in the form of dead organic material
6. Large population oscillations

Answer 2

This biome has long cold winters and short cool summers. The Arctic tundra has low precipitation (less than 10 inches per year) and drywinds. These conditions make the Arctic tundra a desert-like climate(see climograph). One unique characteristic of the Arctic tundra is permafrost--ground that is permanently frozen.
