Tundra and Taiga (Coniferous Forest)

Tundra average temperatures

• -110 to 50

• 0 to 75

• -10 to 80

• -200 to 0

Producers of the Tundra include:

• coniferous pine, shrubs

• moss, lichen, dwarf trees, small flowers

• deciduous trees, grasses, shrubs

• no producers due to cold temperatures

Match soil characteristics of the Tundra:

• thawed top layer, acidic from decomposing pine needles

• fresh top layer, nutrient rich from snow melt

• permafrost in winter, complete thaw for summer, nutrient rich

• permafrost year round, even under summer soil, nutrient poor

In the brief summer season in the Tundra, how does the environment change?

• pioneer organisms, migratory animals, and freshwater pools

• frozen permafrost, no producers or consumers

• permafrost melts, large land mammals return to large trees

• Land returns to bare rock and primary succession begins

Why does Taiga soil harm many producers?

• consumers graze the forest floor too quickly

• low moisture does not allow growth

• soil has no decomposition for nutrients

• soil is acidic from decomposing pine needles

How are conifer trees of the Taiga (coniferous forest) different than the deciduous trees of the deciduous forest?

• Coniferous trees lose leaves, deciduous trees keep leaves

• Deciduous leaves fall, creating acidity in the soil limiting producers

• Conifer trees keep needles and cones throughout the year

• Coniferous needles fall to the ground, just as deciduous leaves do

Grizzly bear, musk ox, caribou and wolves are found in which biome?

• Temperate Deciduous Forest

• Tundra

• Coniferous Forest

• Grassland
