2. Objectives
1)To provide a description of marine aquatic
biome.
2)To know different principle characteristics,
types and nature of the marine ecosystems

3. AQUATIC BIOMES

4. What we know…

5. BASICALLY, WE HAVE 2 MAIN TYPES OF AQUATIC BIOMES
1.Marine water
2.Fresh water

6. Themarine biomeis an environment
characterized by the presence of salt water. It
is found in all of Earth's oceans and is the
largest biome in the world

7. Aphotic Zone
Photic Zone

8. MARINE ECOSYSTEMS
OPEN MARINE ECOSYSTEM1
OCEAN FLOOR ECOSYSTEM2
CORAL REEF ECOSYSTEM3
ESTUARY ECOSYSTEM4
SALWATER WASTELAND
ECOSYSTEM5
MANGROOVE ECOSYSTEM6

open
ecosystem
Major type of
marine ecosystem
Sea life that float
or swim
The euphotic zone
and extends to a
depth of about
150 meters

10. Ocean
Floor
Ecosystems
Shallow water, sunlight
can penetrate to the
bottom
Certain types of fish,
crustaceans, clams,
oysters, worms,
urchins, seaweed and
smaller organisms
At greater depths
where sunlight cannot
penetrate, organisms
can generate their own
light

11. Coral Reef
Ecosystems
Subtype of seafloor
ecosystem
Found only in warm
tropical waters and
at relatively shallow
depths
About one-quarter
of marine species
depend on coral
reefs for food,
shelter or both

12. Estuary
Ecosystems
Shallow, sheltered
area of a river mouth
where freshwater
intermingles with
saltwater as it enters
the sea
The organisms
inhabiting estuaries
are specially
adapted to these
distinct conditions;
hence, the diversity
of species tends to
be lower than in the
open ocean
Serve an important
function as
nurseries for many
types of fish and
shrimp

13. Saltwater
Wetland
Estuary
Ecosystems
A special type of estuary, as they also
consist of a transition zone between
land and sea
The organisms inhabiting
estuaries are specially adapted
to these distinct conditions;
hence, the diversity of species
tends to be lower than in the
open ocean
Serve an important function as
nurseries for many types of fish
and shrimp

14. Mangrove
Ecosystems
Special types of saltwater
swamps
Characterized by
trees that tolerate a
saline environment,
whose roots systems
extend above the
water line to obtain
oxygen, presenting a
mazelike web
Host a wide diversity
of life, including
sponges, shrimp,
crabs, jellyfish, fish,
birds and even
crocodiles

1. Intertidalzone
•-is where theocean meets the land —
sometimes it is submerged and at other times
exposed, as waves and tides come in andout

17. 1.Pelagiczone
•-includes those waters furtherfrom the land,
basically the openocean

Benthiczone
- is the area below the
pelagic zone, but does not
include the very deepest parts
of theocean

Abyssalzone

-The water inthis
region is very cold
(around 3°C), highly
pressured, high in
oxygen content, but
lowin nutritional

20. What we have learnt…..
Marine Biome is actually a salt water system. There different
zones in marine ecosystems
A large biodiversity in Marine biome exist in photic zone
There are six major types of Marine Ecosystems, namely,
(i) Marine Open Ecosystem, (ii) Ocean Floor Ecosystem, (iii)
Coral Reef Ecosystem, (iv) Estuary Ecosystems, (v)Saltwater
Wetland Estuary Ecosystems and (vi) Mangrove Ecosystem
