living components are dependent to
the environment where they belong
which provides their necessities for

THE BIOSPHERE
It is characterized as a dry and hot
biome.
Receives the least amount of annual
precipitation.
The low annual rainfall is caused
by the lack of moisture in the
wind.
Desert biomes
Receives the highest amount of
precipitation.
Distinctly characterized by a dominant
presence of trees and other flora species.
Forests can be classified as
temperate deciduous, temperate
rain, or tropical rain forests.
Forest biomes
This type of biome exists in areas with
precipitation greater than 25 cm, but not enough
to support trees domination.
The height of grasses is directly dependent to
the amount of rainfall.
Grassland
Characterized as having lack of
tree species because of the
inability of the roots to penetrate
the soil.
The soil beneath is permanently
frozen (permafrost).
Tundra
It is characterized with cone-bearing
trees that are well adapted to the cold
because of their leaves that have thick
coverings.
Taiga
BIOMES
Taiga covers about 11% of the land
mass of this planet making it the
world’s largest terrestrial biome
Taiga
The aquatic biome is divided into freshwater and
marine regions.
Aquatic
BIOMES
Freshwater regions, such as lakes and rivers, have a
low salt concentration.
Marine regions, such as estuaries and the
ocean, have higher salt concentrations.
