Abiotic Factors: Physical, or nonliving, factors that shapes an ecosystem
Strong Winds,little precipitaion, short summer days,very long and cold winters, poor soil, and permafrost,a layer of permanently frozen subsoil, altitude, presence of rocks, amount of sunglight, and humidity.

Biotic Factors: Biological influences on organisms within an ecosystem
Plants like Heaths and mosses have to adapt to the very long and cold winters because the sun does not come up in the winter. Wildlife in the tundra includes snowy owls, reindeer, polar bears, white foxes, lemmings, arctic hares, wolverines, caribou, migrating birds, mosquitoes, and black flies.

Density Dependent Limiting Factors: Density Dependent factors are characteristics that are influenced by the size of a population. Density-dependence generally regulates populations within ecosystems that have many species, if they are not stressed by physical conditions.
This is not typically true of the tundra. Its extreme climate reduces the number of species that successfully survive there. Even though this is true, species are still affected by predation and competition in the Tundra.Musk Oxen and Caribou can compete for sedges and grasses. Also, when the population of arctic hares increases the population of artic foxes will go up due to increases predation.

Denisity Independent Limiting Factors: In population ecology, density-independent processes are the result of such physical factors as weather or environmental pollution.
The amount of percipitation: i.e: snow, rain, etc.; Temperature

Producers: Autotrophic organisms that act as a food source for other organisms in a food chain.
Arctic: low shrubs, sedges, reindeer mosses, liverworts, and
grasses,400 varieties of flowers, and crustose and foliose lichen
Alpine: tussock grasses, dwarf trees, small-leafed shrubs, and heaths
