1. A biome is a major region that is

characterized by its climate, soil
type(s), and the dominant plants,
animals, and other organisms that
live there.
 A biome is made up of many
individual ecosystems.

2. Types of Biomes
Tundra

 Desert
 Grassland
 Coniferous forest
 Temperate deciduous forest
 Tropical rainforest

3. Is the temperature of each Biome:
Hot, moderate, or cold?

4. Is the temperature of each Biome:
Hot, moderate, or cold?
Tundra - Cold

 Desert - Hot
 Grassland - Moderate
 Coniferous forest - Cold
 Temperate deciduous forest - Moderate
 Tropical rainforest - Hot

5. Climate
• Weather conditions over a
long period of time

6. Latitude and Altitude Affect the
Climate
Gets colder the higher up you go

(altitude)
 Gets colder the farther north/south of
the equator you go (latitude)
 Most of food on Earth is grown
between 30-60 degrees north and
south of the equator
 -- Do we live in this latitude??--

7. Tundra

8. Tundra
Arctic tundra can be found in

Antarctica and the North Pole, North
of the Arctic Circle.
 Grass, lichen and herbs
 Permafrost – layer of soil that is
always frozen.
 Very short warm season that is very
wet
 Many insects during warm season

9. Coniferous Forest

10. Coniferous forest
Is one of the most fragile biomes

 Spruce and Fir trees
 Found in Northern Hemisphere
 Growing season very short
 Nearly constant daylight in summer
 Many lakes and swamps

11. Temperate Deciduous Forest

12. Temperate Deciduous Forest
Climate and amount of sunlight can

vary
tremendously between each season.
 Deciduous trees lose their leaves in
fall.

13. Grassland

14. Grasslands
Grasslands are characterized by their

tall, perennial grasses and lack of trees.
2 Types

1. Tropical grasslands: between the Tropic

of Cancer and the Tropic of Capricorn, hot
year-round, very dry, season of heavy rain.
2. Temperate grasslands: north of the

Tropic of Cancer or south of the Tropic of
Capricorn, cold winters and hot summers.
Cover a quarter of the land on Earth


15. Desert
• Deserts take up 8.6 million square miles on Earth.

16. Desert
Get less than 25 cm of rain each year

 Has little or no vegetation
 Driest places on earth
 Often located on the dry side of
mountain ranges

18. Tropical Rainforest

19. Tropical Rainforest
Contain over half of the world's plant

and
animal species live here. All fit into
only
7 percent of the world's land.
Found in: Central Africa, Southeast

Asia,
Philippines, New Guinea, Central and
South

20. Tropical Rainforest
Layers:

 Top – Emergent layer – tallest trees
above rest of forest
 Next – Canopy – top of normal trees
 Lower canopy – epiphytes – plants
that grow on tree trunks – not soil -
because light is so far from ground.
 Understory – lowest level, much
darker

21. Climatograms
 A climatogram is a graph that
shows average monthly values for
two factors: temperature and
precipitation.
 Temperature is expressed in
degrees Celsius and is plotted as a
smooth curve.
 Precipitation values are given in
centimeters and are plotted as a
histogram.
