Biomes 3

Biome

Back 1

terrestrial environment defined by the
growth forms of its plants.

Front 2

Whittaker’s Biomes

Back 2

are defined by their
vegetation structure, and can be described as
functions of temperature and precipitation

Front 3

Tundra

Back 3

Arctic and at high elevations. Vegetation is
low-growing perennials.
Arctic tundra is underlain by permafrost.
Soils can be wet because of poor drainage.
Animals migrate or go dorma

Front 4

Boreal/Temperate
Evergreen Forest

Back 4

Long, cold winters; short summers.

Dominated by evergreens in the Northern
Hemisphere: can start photosynthesis
quickly in the short growing season.

Have only a few tree species. Dominant
mammals, (e.g., moose and hares, eat
leaves).

Front 5

Temperate
Deciduous
Forest

Back 5

Precipitation is distributed evenly, but
temperatures fluctuate dramatically.

Forests dominated by deciduous trees that
lose leaves during the cold season.

Temperate forests with the most species
were not covered by glaciers during the
Pleistocene.
