Arctic Tundra Flashcards
Arctic tundra
It circles the North Pole and extends south to the taiga, is cold, dry, and desert-like.
Arctic tundra organic matter and pollutants
Organic matter and pollutants decompose slowly in cold, dry conditions.
Arctic tundra
Growing season
The very short growing season averages around 50 days per year.
Arctic Tundra summer temperature
This biome survives because summer temperatures range from 37°F to 54°F (3°C to 12°C)
Arctic Tundra winter temperature
and winter temperatures average –30°F (–34°C).
Arctic Tundra precipitation
Yearly precipitation, including melting snow, is 6 to 10 inches (15 to 25 cm).
Arctic Tundra soil
The thin, shallow, easily compacted, nutrient-poor soil forms slowly.
Permafrost
A layer of permanently frozen subsoil.
Artic Tundra how bogs and ponds forms
Bogs and ponds form when water saturates the upper surface, providing moisture for cold-resistant plants like low shrubs, mosses, grasses, approximately 400 flower varieties, and lichen.
Artic Tundra sweeping wind and disturbances in the soil
All plants are adapted to sweeping winds and disturbances of the soil.
Artic Tundra winter plants
Short, clumped plants survive winter snowfall.
Artic Tundra photosynthesize
They can photosynthesize in low light and temperatures.
Artic Tundra plants reproduce
Most plants reproduce by budding and division, not by flowering.
Artic Tundra food webs
Food webs are simple and characterized by low biodiversity.
Artic Tundra winter animals
Animals are highly specialized for long, cold winters and quick breeding and raising young in summer.
