Biomes Flashcards
Terrestrial biomes can be characterized by…
Distribution
Precipitation
Temperature
Animals & Plants
Tropical Forest distribution
in equatorial & subequatorial regions
Tropical Rain Forests precipitation
constant rainfall
Tropical Dry Forests precipitation
highly seasonal
Tropical Forest temperature
high year-round - 25-29°C
little seasonal variation
Desert distribution
in bands near 30° north and south equator
in the interior of continents
Desert precipitation
low
highly variable
less than 30 cm per year
Desert temperature
may be hot or cold
Desert plants adaptation
adapted for heat and desiccation tolerance
water
water storage
reduced leaf surface area
Many animals in desert are diurnal or nocturnal?
nocturnal
Savanna distribution
in equatorial and subequatorial regions
Savanna precipitation
seasonal
Savanna temperature
24-29°C
more seasonally variable than in the tropics
What make up most of the ground in Savanna?
Grasses and Forbs
Savanna plants adaptation
fire-adapted
tolerant of seasonal drought
Chaparral distribution
in midlatitude coastal regions on several continents
Chaparral precipitation
highly seasonal
rainy winters & dry summers
Chaparral temperature
30° C summer
10-12°C fall, winter, spring
Chaparral plants adaptation
adapted to fire & drought
