What are biomes?
The biosphere is divided into
major areas called biomes.
• A biome is determined mainly by its
climate-like temperature and rainfall.
• Each biome has a different climate, which,
in turn, affects the soil.
• The earth’s land areas are divided into 6
• Bitterly cold and covered with snow and
• Ground remains permanently frozen
• Only certain small plants such as mosses
and grasses can grow.
• Some animals like reindeer and foxes
move in during the growing season.
2. CONIFEROUS FOREST
• Confers = cone-bearing trees (pines, fir)
• Cold climate
• Dense forests (tree tops block out a lot of
• Grasses, small trees cannot grow – only
some shrubs, ferns and mosses thrive.
• Animals such as squirrels, moose, birds,
and insects live here.
3. DECIDUOUS FOREST
• Maples and oaks – shed leaves in Fall.
• Thrive in moderate climates.
• Summers may be hot and winters may be
• Receive a good supply of water.
• Dense forests
• Provides habitats for many animals.
4. TROPICAL RAIN FOREST
• Very warm and very moist all the time.
• Receives plenty of sunlight and rain.
• Excellent for plant growth and soil
• Plants grow thick and tall.
• Found in areas near the equator.
• Support more plant life and animal species
than any other biome.
• Mostly grass!
• Temperatures similar to deciduous forest.
• Do not receive much rainfall – enough rain
to support grasses but not trees.
• Excellent for grazing animals.
• Soil is very rich.
• Wheat and corn grow here.
• Home for many small, burrowing animals.
Very dry; receives very little rainfall.
Very hot during the day, cold at night.
Soil is very dry and poor.
Only a few kinds of plants grow in the
