Transcript of Biomes

photo credit Nasa / Goddard Space Flight Center / Reto Stöckli BIOMES Climates of the World Climate Zones Three Major Climate Zones of Earth- Tropical Rainforest Has the most precipitation of all the Biomes. Tropical Desert This is a hot desert but cold deserts also exist. Temperate Zone Climate zone between the Tropics and Polar zone.
*United States is in a Temperate Zone. Temperate Grasslands Also known as... Chaparrals Polar zone Temperate zone Tropical zone Tropical Zone- Warm zone around the equator.
Receive the most solar radiation.
Temperatures are hot.
In these zones there are three types of BIOMES. Tropical Rainforest are always warm and wet.
Tropical Rainforests are the most biologically diverse biome.
Soil is thin and poor, with little nutrients.
But organisms decay quickly, and give nutrients to plants. Deserts receive less than 25cm. of water per year.

Here Plants grow far apart to reduce competition for
water!! Daily temps. range from 50 Degrees Celsius at daytime
to 20 degrees Celsius. Soil is poor due to the dryness preventing decomposition. jackrabbit Gila Monster Roadrunner Tropical Grassland Also known as grasslands, they are dominated by tall grasses and scattered trees. The climate is usually very warm.
There are dry seasons that last 4 to
8 months. Followed by periods of rain. The Savannah is home to some of the largetst plant eaters in the world. Zebra Soil nutrient is poor, but grass fires leave the
soil nutrient rich. Average Temp. 27 Celsius to -32 Celcius
Average rainfall- 100 cm per year. Monkey Scarlet macaw Panther Gila Monster Temperate Forest High amount of rainfall averaging 76-250cm
per year.
Seasonal changes.
Warm summers and Cold winters.
Very rich soil because of the deciduous
trees dropping their leaves. Climax Community
Deciduous Trees - trees that change colors
and lose their leaves with the seasons. Deciduous Forest Taiga
also known as Evergreen, Boreal,
and coniferous forest
because the seeds these trees
produce are cone shaped. Evergreen tree- trees that keep their leaves year-round. Ground Squirrel Brown Bear Ground Squirrel Prairies-
United States steppes-
Eurasia veldts-
Africa Pampas-
South America Temperate Grasslands have warm summers and cold winters.
The Soil is the most fertile of all Biomes.
Tall grasses dominate the community. Chaparrals
Have cool, wet winters and hot dry summers.
Vegetation: evergreen shrubs
Soil is Rocky and poor in nutrients. Temperate Desert Receives less than 25 cm of water per year.
This is a COLD desert.
Temperature at night can be below freezing.
Soil is poor in organic matter. Rattle Snake Water Shrew Ringtail Cat Moose Spotted Salamander Think about it:
Predict what will happen if the tree of a Temperate forest was moved to the Desert. explain. YOU determine:
Temperate grasslands are very fertile (good soil) so the majority of them are being destroyed and used for growing crops.
Do you think this action is a good or a bad idea? Why? Woodpecker Deer Compare the three temperate biomes,
Temperate forest, grasslands, and
deserts. Rate each biome one the
scale of 1 thru 5 to select which one
you would choose if you were a farmer.
1 being least desirable
5 most desirable. ( Also known as Tropical Savanna) (Deciduous)
