Transcript of Biomes Report
- a way to divide
animal and plant life
TYPES OF BIOMES
One type of grassland biome
trees and shrubs absent
having grasses as the dominant vegetation
North of the Tropic of Cancer (23.5 degrees North) and south of the Tropic of Capricorn (23.5 degrees South)
veldts of Africa
pampas of South America
steppes of Eurasia
plains of North America
over 100 degrees Fahrenheit
can be as low as
have between 10 and 35 inches of precipitation a year, much of it occurring in the late spring and early summer.
Grasses are the dominant vegetation
Woody shrubs and trees are not established due to seasonal drought, occasional fires and grazing by large mammals
Grasses are not easily destroyed by fire because of underground stems and buds
6 to 12 inches high
flower stems grow 7 to 18 inches tall
can stand drought, heat, cold, and mowing
used for erosion control
low growing, commonly
only 8 to 10 inches high
both staminate and
ideal grass for those
wanting a "native" landscape.
animals eat grasses
growth point on the grasses is very close to the ground
dominant vertebrates are herbivorous
FOOD CHAIN/ ANIMALS
type of grassland biome
Rolling grassland scattered with shrubs and isolated trees
wet/dry climate (tropical climate & dry season in winter)
→ Dry season in winter
most plants shrivel up and die
→ Wet season
all plans are lush and the rivers flow freely
plants - highly specialized:
long tap roots
trunks (store water)
storage organs (bulbs & corms)
water -stored in its thick, corky, fire-resistant trunk (9 months ahead)
all parts are used (from bark → fruit)
sturdy stem for pollinators
adaptations: tiny wooly hairs on its flowers (holds on water)
long strong neck; very sharp beaks
eats fruits, flowers, seeds, caterpillars
long legs and wings
speed for survival
keep savanna clear
Land Biomes: Climate and Locations of Savannas
** Large range of highly specialized plants and animals
**Grazers can coexist in one area
** People in these areas, started using it to graze their cattle and goats
● also known as Temperate Grassland
● usually an early stage in the natural succession to forests
● regions: chaparral, woodland and savanna.
West coastal regions between 30° and 40° North and South latitude
surrounding the Mediterranean Sea
southwest parts of Africa and Australia
usually found surrounding deserts and grasslands.
shrubs or short trees
Plants have adapted to fire caused by the frequent lightning that occurs in the hot, dry summers.
fast-growing ‘coloniser’ species of plants.
more rain than deserts and grasslands but less than forested areas
not enough rain to support tall trees.
SHRUB: A much-branched woody plant fewer than 8 meters in height and usually with many stems.
