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.
