Biology = the study of life
Objectives
• Define Biome• Identify distinctive plants, animals, and
climatic characteristics of Canadian biomes (tundra, permanent ice, boreal forest, temperate deciduous forest, temperate rainforest, grasslands)
• Identify factors that affect the global distribution of the 8 terrestrial biomes (as above plus desert, tropical rainforest)

Earth 1972 – as seen from Apollo 17
BIOLOGY UNIT = BIOMES
3
= the largest divisions of the Earth’s biosphere
What is a Biome?
4
= any and all of the places on Earth where life exists
- includes all terrestrial and aquatic biomes
What is a Biosphere?
5
- travel- economics- curiosity- survival

Boreal Forest
8
Where is the Boreal Forest?Northern Hemisphere including Canada, Russia, Finland and Scandinavia
9
What is the Boreal Forest like?Climate: temperatures = -40 C – 20 C
precipitation = 20-85 cm annually
Physical: short summersrough terrainwetlands
Plants: mainly coniferous trees (cones and needles)spruce and balsamshady = very little understory
Animals:
10
Temperate Deciduous Forest
11
Where is the Temperate Deciduous Forest?
Eastern Canada, Eastern USA, Western Europe, Eastern Asia
12
What is the Temperate Deciduous Forest like?
Climate: temperatures = -30 C – 30 Cprecipitation = 75-180 cm annually
Physical: extreme seasonslong, warm growing seasonrich soil
Plants: deciduous and conifersgrow in 4-5 layersmaple, oak, birch, short trees, shrubs, ferns, herbs and mosses
Animals:13
Temperate Rain Forest
14
Where is the Temperate Rain Forest?
West Coast of Canada, USA and South America and Southern Australia, New Zealand
15
What is the Temperate Rain Forest like?
Climate: temperatures = 5C – 25 Cprecipitation = over 200 cm annually
Physical: along coasts that have mountainslong cool, wet seasons
Plants: deciduous and coniferstrees can grow extremely tallmosses, lichens, ferns and fungivery shady in forest
Animals:
16
Tropical Rain Forest
17
Where is the Tropical Rain Forest?band around the equator including Central America, Central Africa and Southeast Asia
18
What is the Tropical Rainforest like?Climate: temperatures = 20 C – 35 C
precipitation = over 250 cm annually
Physical: poor soilextreme rainforest floor very shady
Plants: grow in many layersplants grow on other plants to get to sun
Animals:
19
Grassland
20
Where is the Grassland?Canada, USA, Russia, Africa, South America, Northern Australia
21
What is the Grassland like?Climate: temperatures = -10 C – 30 C
precipitation = 25-100 cm
Physical: flat lands (prairies)very rich, fertile soilwind can cause soil erosions
Plants: few trees due to lack of raindeep rooted grassesmany wildflowers
Animals:

26
Where is the Tundra?Upper Northern Hemisphere including Canada, USA, Greenland and Russia
27
What is the Tundra like?Climate: temperatures = -30 C – 12 C
precipitation = less than 25 cm annually
Physical: has a layer of permanently frozen soil = permafrostflat, poor drainagepools and marshes
Plants: no treesshort grasses, lichens and mossesshrubs and short flowers
Animals:

Permanent Ice
29
Where is the Permanent Ice?Arctic, Greenland (ironic ) and Antarctica
30
What is the Permanent Ice like?Climate: temperatures = -30 C – 15 C
precipitation = less than 50 cm annually
Physical: very strong windsvery little soilvery little fresh water (frozen)
Plants: lichen and mossflowering plants (mostly Arctic)
Animals:

BIOMES PROJECTPurpose: to learn more about factors that affect and influence the characteristics of the different biomes
Approach: a combination of guidance and freedom to discover and demonstrate your own knowledge
Meaning: 1. Pick a biome to focus your attention on2. Each day Dr. T will present a mini-lesson3. Each day you will apply that mini-lesson to your chosen
biome…you will have to “show what you know” using info about your chosen biome
- some days…given strict guidelines- other days…given FREEDOM!4. Hand in all assignments on time…I will assess and give feedback
so you can make corrections before final submission…DO NOT THROW ANYTHING AWAY!
5. Final class of unit…assembly time…your choice
32
BIOMES PROJECTPartners: allowed and encouraged
Be careful: for some parts of the project each partner will have to complete and submit their own copy of the assignment
- READ ALL DIRECTIONS CAREFULLY!
Be careful: Pick a reliable partner who you can work with outside of class time if necessary
33
BIOMES PROJECTClass Time: must be used productively
Be careful: you DO NOT have the option to say “I will work on this at home”…you must be working in class!
