Tropical Rain Forest
•
•
•
•
•
•
Average rainfall of 50 to 260 inches
yearly
– Often more than 100 inches
Temperatures generally range from 68*F
to 93*F
4 layers of strata
Mostly found near the equator
Mostly trees, but a variety of vine species
and shrubs
Insects, mammals, birds, amphibians
and reptiles, but insects are the most
abundant
Savanna
•
•
•
•
•
•
•
Winter- About 4 inches of rainfall
Summer- Average rainfall of 15 to
25 inches of rainfall
Warm temperature year round,
that rarely drops below 70 even in
the winter
Rolling grasslands
Found on either side of the
equator at the edge of tropical
rainforests
Animal and plant life depends on
the location of the savannas
Shrubs and isolated trees
Generally large herds of
mammals live on savannas
Deserts
•
•
•
•
•
•
•
•
•
Hot deserts- About 15 cm yearly
Cold deserts- About 15-26 cm yearly
Temperature of Hot and dry deserts range from 68*F to 77*F
The maximum temperature of Hot deserts ranges from 110*F to 120*F
Cold deserts range from 28*F to 39*F in winter and from 70*F to 79*F in summer
Deserts are usually large areas of land with sand and little plant and animal life
due to extreme temperature conditions
Hot and dry deserts are found mostly near the Tropic of Cancer and Tropic of
Capricorn, and cold deserts are found mostly in artic areas
Vegetation is rare in hot and dry deserts, and in cold deserts about 10% is plants
mostly deciduous or contain less spiny leaves
In hot and dry, and cold deserts only animals that are burrowers can survive to
escape from extreme temperature conditions
Also in hot and dry deserts there are small nocturnal carnivores, insects,
arachnids, birds and reptiles
Chaparral
•
•
•
•
•
•
•
Very hot and dry, meaning little to no
rainfall
Drought and fires happen quite often
Winter- Around 50*F
Summer- Around 104*F
A variety of terrain such as rocky hills,
flat plains, and mountain slopes
The chaparral is found on each
continent in little areas
Plants with adaptations of small, hard
leaves that hold moisture
Animals that have adapted to the hot
weather of the chaparral, mainly
grassland and desert species
Temperate Grassland
•
•
•
•
•
•
Little rainfall typically between 10
to 20 inches yearly, a lot of
droughts and fires occur, but
enough rainfall for grasses and
some small trees to survive
Temperature depends on location
Rich mix of grasses and forbs and
underlain by the world’s most fertile
soil
Found in middle latitude, towards
the middle of continents
Hundreds of species of plants live
in the grasslands
Also many types of animals live in
the grasslands depending on which
type
Temperate
Deciduous
Forest
• Average yearly temp is 50*F
• There are 4 distinct seasons
• Average rainfall of 30 to 60 inches
yearly
• Very fertile soil
• Locate mostly in the northern
hemisphere
• A large variety of trees, flowers shrubs,
mosses, etc.
• Animals are generally either nut and
acorn feeders, or omnivores
Taiga
(Coniferous
Forest)
•
•
•
•
•
•
Winter- Temperatures range from
-65*F to 30*F
Summer- 20*F to 70*F
Annual precipitation is about 12-33 inches
yearly
Forest with many trees and mountains
Located in North America and Eurasia,
overlying areas that were formerly
glaciers
Not a lot of species of plants in the taiga
due to extreme conditions, most plants
are coniferous trees
Animals of the taiga tend to be predators
Tundra
•
•
•
•
•
•
•
•
Vast treeless land that covers 20%
of earth’s surface
-18*F annually
Earth’s coldest and driest biome
6-10 inches of precipitation yearly,
mostly snow
Located in the northern
hemisphere, encircling the north
pole and extending south to the
coniferous forests of the taiga
Barely any plants, the common
plants are shrubs, sedges, lichens,
and grasses
There are a lot of animals in the
tundra, not many species but they
are abundant
They are animals that feed on the
lichens and plants of the tundra
