IN THIS PRESENTATION I HAVE SHOWN ABOUT AQUATIC ECOSYSTEM . AND SOME INFORMATION ABOUT ECOSYSTEM

2. ECOSYSTEM
WHAT IS ECOSYSTEM ?
 All plants , animals and human beings depend on their
immediate surroundings . Often they are also interdependent on
each other. This relation between the living organisms as well as
the relation between the organisms and their surroundings form
an ECOSYSTEM.

3. Main Types Of
Ecosystem `
1) FOREST ECOSYSTEM
2) GRASSLAND ECOSYSTEM
3) AQUATIC ECOSYSTEM
4) MOUNTAINS ECOSYSTEM
5) RAINFOREST ECOSYSTEM
6) DESERT ECOSYSTEM

ECOSYSTEM

7. BIOTIC FACTORS OF
AQUATIC ECOSYSTEM
 BIOTIC FACTORS OF AQUATIC ECOSYSTEM
means the living creatures in an aquatic
ecosystem . Like all ecosystem , aquatic
ecosystem have 5 biotic factors –
PRODUCERS , CONSUMERS ,
DECOMPOSERS , HERBIVORES ,
CARNIVORES AND OMNIVORES . Biotic
factors include animals , plants , fungi ,
bacteria .

15. ABOUT THE ANIMALS
 The animals living in aquatic ecosystem are called
aquatic animals .
 The aquatic animals either breathe air or breathe
with the oxygen dissolved in the water through GILLS
or SKIN.
 The term MARINE is used to describe the animals
that live in salt water i.e oceans and seas
 For example : SNAILS , SQUID AND MANY SPECIES
OF FISH .

16. AQUATIC PLANTS
 Aquatic plants are the plants that
have adapted themselves to live in
AQUATIC environment .
 They are also referred as
HYDROPHYTES or
MACROPHYTES
 MACROPHYTES are the plants
that grow in or near the water and
produce oxygen and also act as a
food for many fishes and wildlife .
 Aquatic plants can only grow in
water or on soils that is frequently
saturated with water.

17. SPECIES OF AQUATIC
ANIMALS
 There are over 1 million species
present in AQUATIC
ECOSYSTEM .
 There are 32,000 species of fishes
in aquatic ecosystem.
 The species include
REPTILES,AMPHIBIANS and
MAMMALS .
 Some examples are : GOLDFISH ,
BLOBFISH , NORTHERN PIKE .

18. SPECIES OF AQUATIC PLANTS
 There are mainly 4 types of aquatic
plants .
 They are : ALGAE , FLOATING ,
SUBMERGED AND EMERGED PLANTS
 ALGAE are the most common type of
aquatic plants . They are found in
primarily in the oceans and they have no
roots , stems or leaves .
 FLOATING plants are not attached to
the water but they have roots which
absorb water. They can be found in fresh
or salt water .

19.  Submerged plants are rooted to water floor
and most of their vegetation is located
underwater. The leaves of the plants are thin
and narrow
 Emerged plants are rooted to the ground to
the water but have most of their vegetation
above water . These plants need constant
exposure to sunlight .
 SOME ALGAE PLANTS ARE: MUSKGRASS
 SOME FLOATING PLANTS ARE: LILLY
 SOME SUBMERGED PLANTS ARE:
HYDRILLAS
 SOME EMERGED PLANTS ARE: REDROOT
