 THE ENVIRONMENT OF OUR EARTH HAS A
NUMBER OF LIFE ZONES THAT SUPPORT BIRTH
ORGANISMS.
 ALL THE LIFE ZONES OF THE EARTH ARE
COLLECTIVELY CALLED AS BIOSPHERE
 THE BIOSPHERE VERTICALLY EXTENDS INTO
THE ATMOSPHERE UPTO ABOUT 10KM AND
DOWNWARDS INTO THE OCEANS UPTO DEPTH
OF 10.5KM
 IT EXTENDS UPTO THE DEPTH OF ABOUT
6.9KM.

 FORESTS PLAY A SIGNIFICANT ROLE IN MAINTAINING AND
REGULATING WEATHER CONDITIONS OR THE MICROCLIMATE OF A PARTICULAR AREA.
 THEY PROTECT LAND AGAINST WASHED AWAY BY RAINS
OR WINDS.PROVIDE TIMBER, FODDER, MEDICINES, FRUITS,
SEEDS,GUMS,RESINS,DYES,CHARCOAL AND VARIOUS
OTHER PRODUCTS
ALL THE ECOSYSTEM OF A PARTICULAR AREA IS CALLED
AS “BIOME”
 IT CONTAINS BIOTIC & ABIOTIC COMPONENTS
 PRODUCERS:grasses,herbs,shrubs
 CONSUMERS:These includes:1)PRIMARY CONSUMERS-herbivores feeding
on grasses. Example:deers
2)SECONDARY CONSUMERS-snakes, lizards.
3)TERTIARY CONSUMERS- hawks,owls.
 DECOMPOSERS:Various types of saprophytic fungi
 ABIOTIC COMPONENTS:Organic & Inorganic components in the
soil,atmosphere.
 BIOTIC COMPONENTS:These include Producers,
Consumers,& Decomposers.
1)PRODUCERS:Speceis of trees like Acacia.
2)CONSUMERS:
1)PRIMARY CONSUMERS-herbivores feeding on grasses.Eg:rats
2)SECONDARY CONSUMERS-snakes, lizards.
3)TERTIARY CONSUMERS- hawks,owls.
 ABIOTIC COMPONENTS:Soil,sun-light.

LITTORAL ZONE:The shallow water zone of a pond
or a lake is called littoral zone.
LIMNETIC ZONE:This is the well lighted & open
zone.contain algae,free-floating plants
PROFUNDAL ZONE:This is the dark zone of a
pond or lake.Tortoise & big fish rest in this zone.

• Ecosystem of oceans & salt lakes are
called as Marine Ecosystem.
• It is divided into Open sea & Coastal
Ecosystem.
• ESTUARIES are the ecosystems found
in the junction areas of soft & marine
waters.
ECOSYSTEM DIVERSITY OF
INDIA
 INDIAN ECOSYSTEMS & THEIR DIVERSITY IS USUALLY AT
THREE LEVELS
 MAJOR NATURAL HABITATSFORESTS,GRASSLANDS,DESEARTS,WETLANDS(INCLUDING
ESTUARIES,MANGRAVOES,CORAL REEFS&MARINE)
 HIGH MONTAIN RANGES ( BIOTIC PROVINCES :TRANSHIMALAYA,NORTH-WEST HIMALAYA,EASTERN
HIMALAYA,INCLUDING NEINDIA) & ISLANDS.
 BIOGEOGRAPHIC REGIONS-WESTERN GHATS,DECCAN
PENINSULA,EASTERN GHATS(ECO-REGION).

IF WE WANT TO SAVE OUR PRECIOUS BIOSPHERE
THEN IT IS IMPORTANT TO STUDY ECOSYSTEMS
