Limiting Factors

Plants and animals will be affected the same regardless of their population size


  • Mutualistic- Bees and Flowers: The bees are receiving food from flower while pollinating them
  • Commensal- Moss and Trees: The moss is receiving a cool place to flourish while the tree remains unharmed.
  • Parasitic- Wintertick and Moose: The wintertick receives food from the moose as it sucks its blood, this causes harm to the moose.

Abiotic and Biotic Factors

Abiotic- Rocks/Mountains, Sun, Lakes/Ponds, Snow

Biotic- Bears, Coniferous Trees, Moose/Elk, Wolves

Adaptions for Animals

•Some animals hibernate when temperatures drop in the winter.

•Animals here produce a layer of insulating feathers or fur to protect them from the cold temperatures.

•Some of the larger animals have large, wide paws, so they wont sink in the snow.

Adaptions for plants

•Evergreens don’t drop their leaves, so they don’t have to use nutrients to regrow them in the spring.

•The evergreen leaves are needle-like so they don’t loose a lot of water,

because the ground water freezes and the roots cant absorb any water.

•The conical shape of evergreens allows snow to easily slide off branches, so the branches don’t break.

Interesting Facts

•For six months out of the year the temperature is below freezing.

•Scientists believe the taiga was completely covered by glaciers, many years ago.

•Many animals that live there can change color based on time of year.

•The switch from winter to summer is extreme, because spring and fall are too short to notice.

Taiga and Tundra comparison


Both taiga and tundra are in the higher latitudes (arctic), though taiga is considered subarctic. Both are very cold. Tundra has permafrost (permanently frozen soil), but the more northern taiga does, too. Both tundra and taiga don't have very good drainage, and so the land is often wet. Both have counterparts in the mountains of more temperate latitudes.


Tundra has no trees, and only low vegetation like grass, moss, lichens, and shrubs. Taiga has trees like spruce and fir. It is slightly warmer than the tundra and located farther south. tundra is desert and has less precipitation than the taiga. The tundra is often on the coast farther south where there is taiga
