The word tundra derives from the Finnish word for barren or treeless land. The tundra is the simplest biome in terms of species composition and food chains.
Vegetation: lichens, mosses,sedges, perennial forbs, and dwarfed shrubs, (often heaths, but also birches and willows).
Growthforms: typical are ground-hugging and other warmth-preserving forms including:
Climate: The high latitude conditions of Koeppen's ET climate type that impact life in this biome include
Edaphic controls: Permafrost, not cold temperatures per se, is generally believed to be what prevents tree growth. Furthermore, freeze-thaw activity, a thin active layer, and solifluction during the warmer months contribute to strong controls on vegetation patterns and create a mosaic of microhabitats and plant communities.
Soil: No true soil is developed in this biome due to the edaphic factors mentioned above.
Fauna: Strategies evolved to withstand the harsh conditions of the tundra can be divided among those species that are resident and those that are migratory.
Aperiodic emigration from the tundra is exhibited by the snowy owl during those years that the lemming populations have crashed. Those winters see snowy owl irruptions as far south as Virginia. Most owls are found with empty stomachs and do not survive to return to the Arctic.
Distribution: The tundra biome is restricted to the high latitudes of the northern hemisphere in a belt around the Arctic Ocean. Many of its species, both plant and animal, have circumpolar distribution areas.
Within the tundra biome a latitudinal zonation of communities is realized:
In the tropics, the climate of very high elevations is extremely different than that of the Arctic. Freeze-thaw, instead of following a seasonal cycle, follows a diurnal cycle. Also, the peaks are isolated from the Arctic tundra. Often endemic species derived from a tropical flora or from Antarctic flora create the unique communities of tropical high mountain tops.

The arctic tundra has poor soil
the water here is usually fresh but can be salty from oceans
If you were to compare it to Arctic soil...Usually in cold places.... soil have methane ,soil in cold places releases methane... or parafrost
The reason why there are no trees in the tundra is because the soil is permanently frozen. This is called the Permafrost.
The tundra has permafrost because the soil in the tundra is very poor. This is why there are not many trees or plants that grow very tall in the tundra. Permafrost is the top layer of soil that is frozen. Obviously there's permafrost because in the tundra it is very cold and the soil is not very rich.

tundra
Tundra (primarily near the north and south poles) is the biome that is frozen with very little precipitation or vegetation....
The Arctic Tundra has a layer of frost called permafrost beneath the soil, The soil is very thin and only dwarf things can live in it.for example:shrubs lichens and mosses.also there is only one type of tree that lives threre it is called the dwarf willow tree. This will answer you question and more.
the soil is permafrost, and the soil is low in mineral
