2. Ecosystem

3. An ecosystem is a biological environment consisting of all the living things in a particular area, as well as all the nonliving (abiotic), physical components of the environment with which the organisms interact, such as air, soil, water and sunlight

4. Coastal ecosystem
The coastal ecosystem lies where the land and ocean meet
Coastal

5. Ocean
Land
Coastal
The processes are :
Tidal
Wind
Salt intrusion
Land
Ocean
Coastal
The processes are :
Sedimentation
Runoff
Water stream

6. Physical component in coastal ecosystem
1. Water Structure
Interaction between sea water and pollutant :
Missible
Immissible
Partial immissible

7. 2. Chemical component in the sea water

8. 3. Dissolved gasses
- Nitrogen
- Oxygen
- Carbon dioxida
4. Density
Density in the sea water was influenced by :
- Temperature
- Salinity
- Pressure
5. Salinity
Generally defined as the salt concentration (e.g., Sodium and Chlorure) in sea water. It is measured in unit of PSU (Practical Salinity Unit)

9. 6. Sunlight
Sunlight is penetrated in the water bodies up to 100 m depth in the clear sea water
7. Wave
a wave is a disturbance that travels through space and time, usually accompanied by the transfer of energy

10. 7. Sea current
Sea current is a complex phenomenon which influenced by wind, and heat. Hence, sea current is a effective media to distribute and dissolve marine pollutant.

11. Biological component in coastal ecosystem
Plankton
Nekton
Benthos

12. Ecosystem in the coastal environment
Mangrove is a non-taxonomic term used to describe a diverse group of plants that are all adapted to a wet, saline habitat.
The approximately 50 mangrove species that are found worldwide belong to 20 genera in 16 families, although two families, Avicenniaceae and Rhizophoraceae, dominate in number of species and abundance.
Mangroves extend over 18 million hectares worldwide, covering a quarter of the world's tropical coastline.

13. Avicennia sp.
Rhizapora sp.

14. Coral Reef The most diverse and beautiful of all marine habitats
They lives in warm, clean and shallow waters
They are a home for many marine habitats

15. Corals can build three types of reefs:
Fringing: grows close to shore
Barrier: also grows close to shore but has a lagoon separating it from the shore
Atoll: a ring of coral that surrounds a lagoon, often grows on a submerged mountain or volcano

16. Sea grass
Seagrasses flowering plants from one of which grow in marine, fully saline environments.
Four plant families (Posidoniaceae, Zosteraceae, Hydrocharitaceae, and Cymodoceaceae)
Seagrass ecosystems provide habitats for a wide variety of marine organisms, both plant and animal; these include meiofauna and flora, benthic flora and fauna, epiphytic organisms, plankton and fish,
