Tuesday 2

1. Tuesday 2/17/09 Agenda: Biome Notes HW: Biomes Handout Warm-up: In your book, find out what the layers of trees in the Tropical Rain Forest are called.

2. Monday 2/23/09 Agenda: GR Pg199-202.17-3; #1- 24 Test Review HW: Finish GR if not done in class Warm-up: Do �Sharpen your Skills� on pg.602 of your book. Explain in complete sentences.

3. Agenda: Test Review HW: Finish Review Warm-up: Below are two similar species. List three differences in their adaptations and say to what biome each would be best adapted. Tuesday 2/24/09

4. Biomes

5. What is a Biome? Group of ecosystems with similar climates and organisms. Different environments support different types of organisms

6. Climograph of North American Biomes

8. Biomes of the World Rain Forest Desert Grassland Deciduous Forest Boreal Forest Tundra Freshwater Marine

9. Rain Forest Biomes Most are close to the equator Warm and humid Large amounts of precipitation Two types: Tropical and Temperate

10. Tropical Rain Forest Found in warm regions close to equator Lots of rain, sun and heat Scientists have discovered over 300 different kinds of trees in a 100 meter square

11. Tropical Rainforest Climograph

15. Layers of the Tropical Rain Forest Tall trees form a leafy roof called the canopy A few giants will poke out above the canopy Below the canopy is the second layer of shorter trees and vines called the understory Ground level plants grow in the forest floor

16. Temperate Rain Forest Receives more than 300 centimeters of rain a year Huge trees such as Cedars, Redwoods and Douglas firs

17. Temperate Rainforest Climograph

20. Desert Biomes Receives less than 25 centimeters (10 inches) of rain per year. Plants and animals must adapt, due to lack of H2O Majority found near 30o north and south latitude

21. Desert Climograph

22. Deserts of the United States

25. Grassland Biome Areas where grasses are the dominant plant Also known as the Prairie: Humid and densely covered in tall grass Steppe: A drier climate Savannah: warmer and dry with seasonal droughts This biome is where most of the world�s food is grown

26. Grassland Climograph

29. Temperate Forest Biomes Deciduous trees are the predominant tree Every cold season they shed their leaves Some examples of these trees are oaks and maples Generally cold in the winter and warm in the summer Receive an average of 50 centimeters of rain per year

30. Temperate Forest Climograph

34. Boreal Forest Biomes Colder than Deciduous forest and farther north Contains Coniferous Trees, which produces seeds in cones and have needles for leaves Also known as the taiga Winters are very cold

36. Boreal Forest Climograph

40. Tundra Biomes Extremely cold all year long May receive as little precipitation as the desert Most of the soil is frozen all year, called permafrost

42. Tundra Climograph

45. Comparison of Rainfall Amounts

46. Freshwater Biomes Includes ponds, lakes, streams, and rivers Only enough light for photosynthesis near the surface of shallow water Algae is the most common producers

47. Marine Biomes Type of organisms depend on the depth of the water The levels differ in sunlight amount, water temperature, wave action and water pressure.

50. Types of Marine Habitats Estuary Shallow sunlit water Intertidal Zone Rocky shoreline Between high and low tide Neritic Zone Extends to the edge of the continental shelf Relatively shallow water out in ocean

51. More Marine Habitats Oceanic Zone Over oceanic basins Abyssal plain The bottom of the oceanic basins Completely dark Many bizarre animals
