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)
Serengeti safari
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.
PRAIRIES
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.
