Is Life uniformly distributed?

•

Is life evenly spread out?

• The biosphere is everything on earth that supports life.

• Here is a picture of the • different levels in which life is

organized. • The levels go from _________

to ________? (smallest, largest)

Biosphere

Biomes1. Biomes are the major

climate regions on earth.

2. Each biome has different kinds of plants and animals.

3. Deserts, rainforest etc. are examples of biomes

THE BIOMES OF THE WORLD

KEY

Each Biome has a different climate1. Biomes are different climate

regions

2. Latitude (how far N or S) and altitude (how high) affect average temperature

3. Every living organism has its “just right” living conditions

4. Average temperature and rainfall determine climate

5. Climate is shown on a graph called a CLIMATOGRAM

How to read a CLIMATOGRAM

• Blue bars are rainfall

Read the cm rain on R y

• Green bars are temperature

Read the degree C on L y

• Along the X axis is

Which month

1. Tropical rainforest

• High temperature and rainfall• No seasons• Lush, dense plants, very green• Biodiverse: full of many

different kinds of animals

and plants!

3. Desert

• Low rainfall• High temperatures• Special plants with

water conserving adaptations• Too few plants

for large wildlife

5. Grassland

• No trees• Typically 4 seasons• Occasional fire• Fertile soils• Many large & small grazers

6. Temperate forest

• Deciduous trees (leaves fall off in the winter)• 4 seasons (cold winter – dormant)• Open forests• Large & small

grazing animals• YOUR BIOME!!

7. Taiga

• Evergreen trees

• Largest biome on earth

• 4 seasons, large amounts of

snowfall

• Large and small grazers;

carnivores

8. Tundra

• “Permafrost” – permanently frozen subsoil• Very cold, high winds• No trees• Low annual rainfall• Animals and plants here

have special adaptations

to survive the extreme cold

TUNDRA•Driest biome on earth•Largest biome on earth•Coldest biome on earth

Exit ticket

• Make a list of as many terrestrial biomes that you can think of without looking at your notes.

• Write 3 words next to each biome that help you to differentiate it.
