– On Land Aquatic Biomes -
Underwater
Aquatic Biomes Marine Biomes-Contain saltwater. The type of
organisms present is highly dependent on sunlight. Sunlight is needed for photosynthesis Photic Zone-Sunlight can penetrate,
Photosynthesis can occur Aphotic Zone-Sunlight cannot penetrate
Terrestrial Biomes Latitude influences
the climate of an area Some latitudes
receive more direct radiation than others
Temperature and precipitation have a huge affect on the climate of an area
Tundra The tundra is a
treeless area in the Arctic circle that is consistently frozen Little vegetation
because soil is often frozen (permafrost)
Organisms: Weasels, oxen, caribou, foxes, reindeer
Taiga Taiga-Lies below the
tundra and is usually warmer and wetter Most of Canada,
Northern Europe, Asia
More trees than the tundra
Weasels, squirrels, elk, moose
DesertDeserts are arid regions with high
temperatures and little rainfallLittle vegetation due to scarce rainfallLife includes cacti, kangaroo rat,
coyotes, snakes, lizards, scorpions
Grasslands Grasslands contain rich soil, grasses and plants
Dry summers Little forests. 25-75 cm of precipitation
Soils have high humus content
Life includes: Bison Rabbits Deer Elk
Temperate Forests Temperate Forests – Primarily covered by trees in
a mild climate Animals include:
Squirrels Rabbits Deer Bears
Rain Forests Rain forests have high
amounts of precipitation and high temperatures Near the equator,
have a wide diversity of life
Contains many species of life that are deadly and poisonous
The rainforest is a very dangerous place
