Ecosystems or Landscapes
Ecosystems Rainforest (Equatorial Climate) The Savannah (Tropical Climate) Desert Landscapes (Hot deserts and Cold
deserts) Mediterranean Landscape
(Mediterranean Climate) Continental Landscape (Continental
Climate) Oceanic Landscape (Oceanic Climate) Polar Landscape (Polar Climate) Mountain Landscape (Mountain Climate)
Desert LandscapesThe lack of water makes vegetation and
animal life scarceSome species have adapted to dry
conditions:CactiCamels
In oasis grow date palmsDeserts are almost uninhabited. Only
some nomads live in deserts (Tuaregs, Mongols, Berbers…)

Mediterranean LandscapeRivers have an irregular flow.
They carry very little water in summerAt other times there are floods
There are trees such as “holm oaks”, “corn oaks” and “pine trees”
There are also shrubs and plants like lavender, thyme, rosemary.
Human activity has changed these ecosystems:Forests have been cut down and have been
replaced by:Wheat fields, olive trees, vineyards, pastures...Irrigated agriculture (fruit and vegetables)Tourism activities
Oceanic LandscapesVegetation is abundant due to regular
rainfallThe landscape is mainly green.There are extensive meadowsDeciduous forests are found in the highlandsTrees are: ash (fresno), oak (roble), beech
(haya)In areas of poor soil there are moors with
shrubs and grass.These landscapes are densely populated and
changed considerably
Polar LandscapesPolar landscapes are characterized by ice
and snow.Vegetation is unable to grow because the
subsoil is almost always frozen.Only animals like seals and penguins can live
near the Poles.Near the temperate zone we can locate the
Tundra landscapes, with:Moss, lichens and small trees.Animals: reindeer, foxes, wolves, moose.

Mountain ClimateVegetation changes with altitude because of
the changes in temperature and precipitation. It is called:
Altitudinal Zonation (Cliserie)The vegetation on sunny slopes is different
from the vegetation on shady slopesVegetation is more abundant windward, than
leeward.The levels are:
