• 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)

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
![Page 7: Is Life uniformly distributed? Is life evenly spread out?](https://reader034.vdocuments.net/reader034/viewer/2022051820/56649e405503460f94b31005/html5/thumbnails/7.jpg)
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
![Page 8: Is Life uniformly distributed? Is life evenly spread out?](https://reader034.vdocuments.net/reader034/viewer/2022051820/56649e405503460f94b31005/html5/thumbnails/8.jpg)
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!
![Page 10: Is Life uniformly distributed? Is life evenly spread out?](https://reader034.vdocuments.net/reader034/viewer/2022051820/56649e405503460f94b31005/html5/thumbnails/10.jpg)

3. Desert
• Low rainfall• High temperatures• Special plants with
water conserving adaptations• Too few plants
for large wildlife
![Page 12: Is Life uniformly distributed? Is life evenly spread out?](https://reader034.vdocuments.net/reader034/viewer/2022051820/56649e405503460f94b31005/html5/thumbnails/12.jpg)

5. Grassland
• No trees• Typically 4 seasons• Occasional fire• Fertile soils• Many large & small grazers
![Page 14: Is Life uniformly distributed? Is life evenly spread out?](https://reader034.vdocuments.net/reader034/viewer/2022051820/56649e405503460f94b31005/html5/thumbnails/14.jpg)

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.
