What is the Marine Ecosystem? Marine ecosystems are among the largest of Earth’s aquatic ecosystems. It covers almost 70% of the earth’s surface. They include oceans‚ salt marsh and intertidal ecology‚ estuaries and lagoons‚ mangroves and coral reefs‚ the deep sea and the sea floor. They can be contrasted with freshwater ecosystems‚ which have a lower salt content. Why is the Marine Ecosystem important? Marine ecosystems are very important in to the overall health of both marine and terrestrial

we have studied and drawn up. The problem with taking these very important ions out of the water is that they are one of the two compounds that calcifiers‚ very small organisms‚ need to survive. Calcifiers‚ which are the base of pretty much every coral reef on the planet‚ need to make shells which is part of their colonies skeleton. This leaves a decision for calcifiers to make: should I expend more energy capturing the decreasing amount of carbonate ions or just give up. Studies show that most calcifiers

was still abundant in marine life. The reefs of Tubbataha soon became a fishing destination with many using destructive techniques‚ such as cyanide fishing and dynamite fishing‚ to maximise catch. In 1988‚ in response to a strong campaign by scuba divers and environmentalists‚ and with the endorsement of the Provincial Government of Palawan‚ then President Corazon Aquino declared Tubbataha as a national marine park – the first of its kind in the country.

Overfishing is a major problem that affects the ecosystem and it occurs when fishing activities reduce fish stocks below an acceptable level. Overfishing can occur in any body of water from a pond to an ocean. Overfishing is also a non-sustainable use of oceans. The populations of many commercial fish species are severely depleted because of overfishing. Overfishing originated after World War II‚ which lead to expanding markets‚ newer technologies‚ and increased accuracy in finding fish (The Nature

forms carbonic acid deposited onto the limestone‚ collapsing it. In contrast‚ the flow and force of storm waves is responsible for the removal/movement of large coral pieces (transportation) and its placement in other parts of the reef (deposition).

Seahorses are very slow‚ they have a top speed of about 5 feet per hour (3). Seahorses are found in shallow areas‚ near the coral reefs‚ seagrass beds etc. They swim by using small fins on their back and behind their heads. Seahorses are the only species on earth where the male gives birth (3). Although‚ they don’t physically look like a fish they share some characteristics with

These environmental effects include urbanization‚ over exploitation of resources‚ coastal erosion‚ deterioration of water quality‚ increased pollution levels‚ deforestation‚ and the destruction of coral reefs‚ mangroves and sea grass beds. Many of these factors reduce the resilience of the ecosystems. Furthermore‚ it should also be noted that the environmental effects are further influence by a lack of environmental evaluation and monitoring in the
