Biomes
Terrestrial Biomes
What is a Biome?
A biome is a large geographical area of distinctive
plant and animal groups adapted to that particular
environment.
The climate and geography of a region determines
what type of biome can exist in that region.
Major biomes include deserts, forests, grasslands,
tundra, and several types of aquatic environments.
Tundra : terrestrial biome
Scientists call TUNDRA the frozen cold ecosystems
found near the North part of the Earth.
Winters are LONG AND COLD. Summers are
SHORT AND COOL.
Animals and plants in the
tundra biome:
Animals: seals, polar bears, arctic hares, and
arctic foxes survive in the long cold winters.
Deserts: terrestrial biome.
There are both hot and cold deserts. Antarctica is the largest desert
in the world, while the Sahara in Africa is the largest of the hot deserts.
Hot and dry deserts
-
-
Most Hot and Dry Deserts don't have
many plants.
They have some plants.
The animals in deserts can survive under
ground.
animals can’t live in the hot sun and
heat. They only come out in the night
when it is a little cooler.
Cold and dry deserts
-
A cold desert is a desert that has snow in
the winter.
Plants don’t grow because is not warm.
The animals in Cold Deserts also have to
live under ground, in this case to keep
warm, not cool
Grasslands: terrestrial biome
-
-
Grasslands have few trees, and extensive
grasses, and many different small and large
animals.
Some of the largest land animals on Earth live
in grasslands, including American bison,
elephants, giraffes, etc.
Rainforest: terrestrial biome
-
-
The tropical rain forest is a forest of tall trees in a
warm region.
Rain forests belong to the tropical wet climate
group.
Rainforests now cover the 6% of Earth's land
surface.
Scientists think that more than half of all the
world's plant and animal species live in tropical
rain forests.
Tropical rainforests produce 40% of Earth's
oxygen.
