Transcript of Biome
-40°F to 64°F
150 to 250 mm of rain per year
Almost no trees due to short growing season and permafrost; lichens, mosses, grasses, sedges, shrubs
Regions south of the ice caps of the Arctic and extending across North America, Europe, and Siberia (high mountain tops) Temperature
-40°F to 68°F, average summer temperature is 50°F
300 to 900 millimeters of rain per year
Coniferous-evergreen trees (trees that produce cones and needles; some needles remain on the trees all year long)
Canada, Europe, Asia, and the United States Temperature
-22°F to 86°F, yearly average is 50°F, hot summers, cold winters
750 to 1,500 mm of rain per year
Broadleaf trees (oaks, maples, beeches), shrubs, perennial herbs, and mosses
Eastern United States, Canada, Europe, China, and Japan Temperature
Average of 102°F (day), average of 24°F (night)
About 250 mm of rain per year
Cacti, small bushes, short grasses
Between 15° and 35° latitude (North and South of the equator); examples are Mojave, Sonoran, Chihuahua, and Great Basin (North America); Sahara (Africa); Negev (Middle East); and Gobi (Asia) Temperature
Dependent on latitude, yearly range can be between -4°F to 86°F
About 500 to 900 mm of rain per year
Grasses (prairie clover, salvia, oats, wheat, barley, coneflowers)
The prairies of the Great Plains of North America, the pampas of South America, the veldt of South Africa, the steppes of Central Eurasia, and surrounding the deserts in Australia Temperature
68°F to 77°F, must remain warm and frost-free
2,000 to 10,000 millimeters of rain per year
Vines, palm trees, orchids, ferns
Between the Tropic of Cancer and the Tropic of Capricorn A biome is an ecological community, like a rainforest, desert, or prairie Your Biome Materials one cup
tape Step 1 Add half an inch of rocks to the cup Step 2 Add an inch to an inch and a half of soil to the cup Step 3 Make a hole in the center of the dirt.
Place 2 seeds in the hole. Step 4 Fill the hole with dirt Step 5 Add water until you see it collect at the bottom of the rocks. Step 6 Place cup in bag. Wrap tape around the cup in the bag. What issues might your biome have? What do plants need to grow? Water
carbon dioxide (CO2) How would you fix the problem? What could vary in your biome compared to the other students in the class? The Water Cycle Why did we wrap tape around the cup in the bag?
