Overview

In this section, include a brief description of the allocated ecosystem. You should include the following information:

• Location of the ecosystem:Ocean
• Description of ecosystem: In the context of Earth, it also refers to major divisions of the planet's World Ocean, such as the Atlantic Ocean. The word "sea" is often used interchangeably with "ocean", but a sea is a body of saline water in a more inland location rather than a location in which it encompasses the land around it.
• Biodiversity of ecosystem (richness of life in ecosystem): 
• Radiata
• Fish
• Cetacea such as whales, dolphins and porpoises,
• Cephalopods such as octopus and squid
• Crustaceans such as lobsters, clams, shrimp and krill
• Marine worms
• Plankton
• Echinoderms such as brittle stars, starfish, sea cucumbers and sand dollars.

Physical Factors

Search the Internet for information on the following physical factors in the allocated ecosystem. 

• Light (availability of sunlight in the ecosystem)
• Temperature (temperature of the ecosystem)
• Water (water quality in the ecosystem)
• Air (quality of air in the ecosystem) 

Classification of Living Organisms

Classify at least eight of the living organisms found in the allocated ecosystem into the categories below:

1. Producers: Seaweed,Seaplant
2. Primary Consumers: razor clam                
3. Secondary Consumers: horseshoe crab, diamondback terrapin
   
4. Tertiary Consumers: loggerhead turtle
   
5. Decomposers: marine worms, bacteria and Marine Seaweed

For each of the living organism, find a picture and write a short description on the organism. You may wish to include feeding habits, region in the ecosystem where it is normally found etc. 

Food Web 

Create a food web using at least eight of the living organisms listed above. You may wish to use Microsoft PowerPoint to create your food web. Save your food web as a picture. Finally copy and paste your picture in this section of your wiki. 

Interrelationship in Ecosystem

Choose and write about one example from the following relationships in the ecosystem:

• Predator-prey relationship: a conger eel eats a wrasse,The conger eel is a top predator and the wrasse is a smaller fish that is eaten, the prey. The sea is a complex ecosystem. Things are eating other things all the time. Usually the food chain goes from small algae like plankton to a small fish like a herring, a mollusc or an arthropod then onto bigger fish. Some big fish get eaten by even bigger ones like sharks.
• Parasitism: whales and intestinal worms,Other parasites include isopods, which are ectoparasites (they live on the outside of their host).
• Mutualism:pilot fish and sharks,pilot fish cleans sharks of parasites. so sharks gets cleaned and pilot fish gets free meal.
