TERRESTRIAL
ECOSYSTEMS
To study the terrestrial
ecosystems, we have to
consider these factors:
- Climate and temperature
- Where we can find them
- Features
- Fauna
- Flora
TUNDRA
It is a very cold and
dry place.
It is located near the North
Pole.
There are no trees
because the soil is very
poor
Reindeer
Arctic
fox
Polar
bears
White
wolves
Lichens
Lichens
Mosses
SAVANNAH
There are two seasons: the
rainy season and the dry
season.
We can find savannahs in tropical
areas, for example in Serengetti
(Africa) or Cerrado (Brazil)

Cerrado in
Brazil
Elephants, lions, zebras,
giraffes, gazelles, etc. live
there.
There are few trees
and lots of grasses.
TEMPERATE
GRASSLANDS
They are located in colder regions
than savannahs.
We can find them in prairies,
steppes and pampa.

STEPPES
PAMPA IN ARGENTINA
There are few trees because the soil is
very poor.
BISON
PRAIRIE DOGS
WOLVES
COYOTES
There are few trees and
lots of grasses.
TROPICAL
RAINFORESTS
It is warm and wet all
year long.
We can find this ecosystem in the tropical area:
between the Tropic of Cancer and the Tropic of
Capricorn.
This ecosystem is the
house of half species of
animals and plants on
Earth.
Snakes, monkeys,
jaguars, parrots, toucans,
etc. live there.
EVERGREEN TREES
FERNS
CONIFEROUS FORESTS
They are located in
cold areas.
We can find them in north Europe.
They are called coniferous because
the seeds of the trees are inside
cones.
There are brown bears,
foxes, deer, etc.
There are
pine trees
and fir trees.
DECIDIOUS
FORESTS
Summers are mild
and winters are mild
too.
We can find them in north America and
north Europe.
Most trees are decidious because they lose
their leaves in winter.
We can find squirrels,
brown bears, rodents,
owls, etc.
There are oak trees.
MEDITERRANEAN
FOREST
There are hot summers and mild winters.
We can find it in areas next to the
Mediterranean Sea.
This ecosystem
suffers from fire,
droughts and
urbanization.
We can find eagles, vultures,
falcons, foxes, etc.
There are cork trees.
DESERTS
It is very hot and dry but nights are
very cold.
We can find them in Africa, Australia, Asia,
etc.
There are hot
deserts, like
Sahara and cold
deserts too.
We can find
lizards,
snakes,
scorpions,
camels, etc.
There are lots of
cacti, bushes, etc.
