Desert biome
1.
2. Deserts are areas that receive very little
precipitation.
Some deserts are very hot, with daytime; other
deserts have cold winters or are cold year-round.
One thing all deserts have in common is that they
are arid, or dry.
In all deserts, there is little water available for
plants and other organisms.
Deserts are found on every continent and cover
about one-fifth of Earth’s land area.
Some deserts are mountainous. Others are dry
expanses of rock, sand, or salt flats.
3. Hot and Dry Deserts
Semi Arid Deserts
Coastal Deserts
Cold Deserts
4. TEMPERATURE: Temperatures in arid areas may get as high as 55
degrees C during the day and as low as 10 degrees C during the night.
RAINFALLAND CLIMATE: The climate of a desert is hot and dry.
The amount of rain in the desert varies slightly from desert to desert, but
on average, desert rainfall measures about 1 inch per year.
ANIMAL LIFE: Although the desert climate is very hot and dry, there
is an abundance of animal life. Varieties of lizards, rats, owls, tortoises,
antelopes and bobcats are just a few of the many desert dwelling animals
that have had to evolve to survive.
PLANT LIFE: there are thousands of plants that flourish in a desert
biome. The two most numerous are the ocotillo, a flowering plant, and
the saguaro cactus.
5. Tundra are tree less plains.
Tundra is the coldest of all the biomes.
Extremely cold climate
Low biotic diversity
Simple vegetation structure
Limitation of drainage
Short season of growth and reproduction
Energy and nutrients in the form of dead organic
material
6. Human economic activity has been scarce on tundra.
Occasional mineral resources, such as fossil fuel and ores
occasionally appear in tundra.
