HSC GEOGRAPHY YEAR 12 EXAM Question 28 (20 marks) ‘An ecosystem at risk is both vulnerable and resilient to natural stress and human induced modifications.’ Discuss this statement For many years wetlands were seen as only a mosquito infested area. Nowadays they are highly valued ecosystems that are being protected for future generations of wildlife‚ and also people. A wetland is an area of land that is temporarily or permanently inundated. Sydney’s Bicentennial Park is home to 58ha of intertidal

DISCUSS THE NATURAL AND HUMAN – INDUCED THREATS TO THESE WETLANDS AND OUTLINE MANAGEMENT STRATEGIES WHICH COULD PROTECT AND SUSTAIN THEM. Mangroves are a type of marine ecosystem. They occur within the intertidal zone of the Minnamurra River estuary. This ecosystem is made up of a community of plants and animals interacting with each other and the abiotic environment. The vegetation of the shoreline is dominated by the Grey Mangrove and the River Mangrove. At the study site‚ both mangroves can

INTERTIDAL WETLANDS • Intertidal wetlands develop in coastal areas which are subject to periodic inundation by salty water • They are found in estuarine environments in the limits of the tidal range • Previously thought of as mosquito infested wetlands‚ they are now considered highly valued ecosystems which protect the quality of coastal waters and provides breeding grounds and habitats for a variety of marine life‚ are found along tropical and sub-tropical coastlines between 25ْN and 25ْC •

quickly‚ oblivious to the consequences that may come. Wetlands are essential resources for the environment. Wetlands provide homes for many animals especially for birds and fishes; it also provides benefits for humans such as flood prevention‚ protection from erosion‚ and provides food. Four hundred years ago around 220 million acres of wetland existed across the 48 states in America by the year 1993‚ 110 million acres remain 50 percent of wetlands have been destroyed due to various reasons some include

"A wetland is land that is saturated with water long enough to promote wetland or aquatic processes as indicated by poorly drained soils‚ hydrophytic vegetation and various kinds of biological activity which are adapted to a wet environment. Are important habitats that provide homes for many endangered species and that they help to control floods and filter some pollutants.

One major ways for the survival of all organisms is called adaptation. When it comes to Intertidal Organisms their no different. Intertidal Organisms inhabit the specific area between low tide and high tide next to the rocks on the coasts‚ marshes and or wetlands. Theses organisms can be from sea stars to types of algae and many more. As the tides come in‚ the habitat of intertidal organisms are sprayed with salt water. Then after the tide depletes‚ the habitat is exposed to the sun. It makes

The Intertidal Zone The intertidal zone is the area of the sea floor that is uncovered and recovered by the tides. At high tide‚ the intertidal zone is submerged beneath sea water and at low tide it is exposed to air. There are two main types of intertidal zones that experience this daily change‚ the sandy shore and the rocky shore. Each has different characteristics and special organisms that survive there. These different species tend to inhabit different zones in which they can handle but there
