2 Terrestrial Biomes Guiding Questions: What factors determine the distribution of different climates around the earth? What factors determine the distribution of different climates around the earth? What are the defining characteristics of the different terrestrial biomes found around the world? What are the defining characteristics of the different terrestrial biomes found around the world? What sorts of specialized adaptations to their environment have organisms in different biomes developed? What sorts of specialized adaptations to their environment have organisms in different biomes developed?

3 How would you describe our local climate? What is our climate like? We have seasons. Our climate is hot & cold depending on time of year. Our climate is TEMPERATE. How would you describe other climates? Warm year round = TROPICAL climate. Cold year round = POLAR climate.

4 These differences in climate around the world lead to different environments for organisms to live in… We call a particular physical environment that contains a characteristic assortment of plants (& animals) a _______. BIOME

5 Distribution of Biomes On Earth

6 Factors Affecting Distribution of Biomes On Earth Uneven heating of earth’s surface by sun

7 How Uneven Heating of Earth Causes Rain and Winds Warm equatorial air rises and spreads northward and southward to produce the initial pattern of air circulation EQUATORS. HemisphereN. Hemisphere

8 Global Air Circulation Patterns Give Rise to Differences in Rainfall at Different Latitudes

9 Mean Annual Temperature and Precipitation for Biomes On Earth Taiga

10 Tundra ( _____ or ______ ) Arctic Alpine

11 Taiga (Coniferous or Boreal Forest)

12 Temperate Deciduous Forest

13 Temperate Grassland (______, _______, _______) PrairieSteppes Pampas

14 Savanna (Tropical Grassland)

15 Tropical Rainforest

16 Chaparral (Scrub Brush Forest)

17 Desert

18 “Other” Biomes… Are all habitat types represented by these biome categories we’ve just seen? The picture shown here looks like a tropical rain forest but is actually found in temperate Washington state. Temperate Rainforest

19 What does the word succession mean??

20 There’s Royal succession…

21 And there’s Ecological Succession… (aka Community Development) The process by which a community undergoes a series of (predictable) changes over time.

22 Primary Ecological Succession Primary succession describes the process by which life can colonize virgin territory and turn barren land into a thriving ecosystem, over a period of time. This occurs when life invades an area with no true soil.

23 Secondary Succession Secondary Succession occurs where vegetation has been removed but soil is intact.
