Tundra is the coldest of all the biomes. It is noted for its frostmolded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons.

Abiotic Factors Of the Tundra
Some of The abiotic factors in the Tundra include: The temperature; Cold/freezing The snow and ice Dirt underneath the ice Some glaciers Some Rocks The Temperature; Cold on average tundras are 300m above sea level
SUMMARY OF ECOLOGICAL SUCCESSION THAT HAPPENS INÂ
Primary: When the earth warmed the glaciers retreated and left behind land that was lifeless and rocky. It took a very long time before plants like lichen started to grow on these rocks. In time, rocks are broken down by the lichens mixed with decaying lichens and formed the first soil. Wind also blew dust, which congregated in small cracks in rocks where moss and small plants started to grow. Secondary:Â When an event, like a fire or natural disaster, reduces an already established ecosystem, but the soil remains and succession then follows. This is faster than primary succession because the soil is already present.

PRIMARY DECOMPOSER IN THE TUNDRA
1. Pored Fungi can be frozen under ice, and still live for years. 2. Pored fungi is deadly, and can cause instant death in humans and animals. 3. Pored fungi keep bugs away from trees and plants.
The Conservation status of Pored Fungi is Least Concern. Pored Fungi have a parasitic relationship with plants and trees. Pored Fungi is growing free in the tundra
CARIBOU Caribou is the only member of deer family where both males and females wear antlers. Caribou is very fast animal it can run 50 miles per hour, especially when trying to escape from the predators. Caribou releases a special scent when faced with danger. The scent is produced in the gland located in the base of ankles and it informs other caribous about near danger. Parasitism is a relation between two organisms where one organism benefits whereas the other one is at a loss in the relationship.
Secondary Consumers The arctic fox can sometimes be a tertiary consumer or a secondary consumer. They eat birds, lemmings, and tundra voles. They use rocky cliffs for dens and in the summer, to camouflage they turn brown. They are about 3-4 feet long and are smaller than you would think.
TertiaryÂ consumers Of the Tundra
Some of the Tertiary Consumers of the tundra are: Hawk Polar Bear Wolf
Organism spotlight Polar Bear
The Polar Bear is a breed of bear that can only be found in the northernmost regions of the world, They are commonly found in Canada, Alaska (US), Greenland, Russia, and Norway. They are under a protected status due to the melting of polar icecaps that act as some of their homes. Did you know that polar bears have a layer of blubber underneath their layer of fur? Did you know that polar bears, besides their weight and size, are excellent swimmers? Did you know that polar bears dig their own dens in the snow?

Tundra In the World
In Love With the Environment One of the ecological threats that the tundra faces isÂ the melting of the permafrost as a result of global warming could radically change the landscape and what species are able to live there. Scientists are studying the subtle and dramatic impacts of human activity and climate change on the tundra to protect theÂ coldest biome on the planet.
