Ecosystems at Risk Ecosystems and their functioning What is an ecosystem? Ecology – the science that examines the interactions between organisms and their living (biotic) and non-living (abiotic) environment. Groups of organisms and their biophysical environment interact and exchange matter and energy. Ecosystem – the dynamic complex of plant‚ animal and micro-organism communities and their non-living environment as a functional unit. Ecosystems are dynamic; constantly changing and adapting

Ecosystems At Risk Reefs are important ecosystems as the are home to an immense amount of biodiversity and are essential in the cycle of life The Role of the Atmosphere Many reefs are located in the cyclone zone due to the necessary conditions they require to grow. For as long as reefs have existed they have been shaped by cyclones and intense storms. The severity of the storms and cyclones is determined by the length and intensity of the storms‚ which determines how much damage will be inflicted

Describe and analyse the biophysical interactions that impact on the Madden’s Creek ecosystem. The Madden’s Creek ecosystem is located at the beginning of George’s River and is found 60km south west of Sydney at an elevation of 350 meters above sea level. About 45% of the catchment contains large tracts of natural bush land. It is home to many species of flora and fauna creating a wide range of biodiversity that interlink and affect each other significantly. In this ecosystem there is a mixture of

Geography Essay The biophysical environment consists of living things such as plants & animals and non-living things such as rocks‚ soils and water. It is the symbiosis between the physical environment and the biological life forms within the environment. The biophysical environment is made up of four overlapping spheres: Atmosphere‚ lithosphere‚ hydrosphere biosphere. As shown in figure (1). These four spheres are dependent upon each other. Each sphere plays a vital role in sustaining

Odessa Tumbali The Interactions and Interrelationships among the Different Components of the Ecosystem I. Introduction Ecology is the study of environmental systems‚ or as it is sometimes called‚ the economy of nature (Hall and Weiss‚ 2010). It studies interactions between different organisms and their environments‚ including relations within its own species and members of others. Ecology focuses more on the population‚ community‚ and ecosystem ecology although it also includes

P3 Draft -Factors which lead to abusive situations Certain groups of people appear to be more vulnerable and susceptible of abuse compared to others. The individuals may suffer from mental health problems or may have physical or learning disabilities‚ the older population tend to be more at risk of abuse as the elderly are weak and frail and cannot often defend themselves especially those with dementia. Any group of individuals who tends to be more at risk of abuse tend and just abide with the abuser
