TERRESTRIAL BIOME PUZZLE KEY TUNDRA TAIGA (Boreal Forest) TEMPERATE DECIDUOUS FOREST TEMPERATE GRASSLAND Strong, very cold winds with little precipitation, short & soggy summers Coniferous forest with long winters but mild summers when ground thaws 4 seasons (spring, summer, winter, fall) warm to hot summers and cool to cold winters -10oC to 14oC Cool year round 6oC to 28oC Has both cool and warm seasons 35-75 cm Adequate Rainfall to support trees 75-125 cm Adequate Rainfall to support trees 25 – 75 cm Wet season and dry season SOIL Thin, nutrient poor soil over frozen Permafrost Low in nutrients and Acidic Moist with moderately thick topsoil, Rich in nutrients (humus) Deep layer of nutrient rich topsoil; Good for farming KEYSTONE SPECIES Artic Fox – food source for a lot of animals Pine, Spruce, and Fir Trees – homes/places to grow for plants & animals White-tail Deer – eat grass/other plants to control their populations N/A HUMAN IMPACT Global warming, melting of permafrost, oil spills Deforestation, climate change Acid rain, deforestation, climate change Global warming, urbanization, pesticide use DESCRIPTION AVERAGE TEMPERATURE -26oC to 12oC cold year round ANNUAL PRECIPITATION <25 cm dry 0oC to 25oC Has both cool and warm seasons TERRESTRIAL BIOME PUZZLE KEY CHAPARRAL DESERT TROPICAL SAVANNA TROPICAL RAIN FOREST DESCRIPTION Mild, rainy winters & hot, dry summers; Called plains; “western movies” Low precipitation with extreme temperature changes ( hot in day & cold at night) Alternating wet and dry seasons with large number of herbivores & lots of migratory animals Located near the equator; called jungles or tropics AVERAGE TEMPERATURE 10oC to 18oC Hot summer & cool winter 7oC to 38oC May be very cold or very hot 16oC to 34oC Always warm 20oC to 34oC Always warm and humid ANNUAL PRECIPITATION < 25cm dry summer & rainy winter < 25cm Very dry year round 75-150cm 6 month rainy season (monsoon) 200-400cm Rains almost daily; long, wet season SOIL Rocky, thin topsoil, low in nutrients Dry, often sandy soil, low in nutrients Dry, thin layer of topsoil; porous; low in nutrients Moist thin topsoil that is low in nutrients KEYSTONE SPECIES Kangaroo rat – burrows serve as homes to other animals Hummingbird pollination Elephant – eat small trees Agouti – only animal to eat brazil tree nuts wildfire Global warming, wildfires, nuclear waste, off-road vehicles Competition from nonnative species, overhunting, climate change, over-farming Deforestation, global warming HUMAN IMPACT
