Tundra
is the coldest of all the biomes. Tundra comes from the Finnish word tunturia,
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. Tundra is separated into two
types: arctic
tundra and alpine
tundra.
Location: - Arctic tundra is located in the northern hemisphere, encircling the north pole and extending south to the coniferous forests of the taiga -Alpine :Alpine tundra is located on mountains throughout the world at high altitude where trees cannot grow. |
