Area+of+Study+2+-+Dynamic+Ecosystems

With an emphasis on Australian ecosystems, this area of study focuses on the complex and finely balanced relationships that exist between living things and the resources in their particular habitat. This network of relationships can be understood as a system with inputs, processing and outputs: there is a flow of energy and cycling of matter between the living and non-living components of the ecosystem. Ecosystems do not exist in isolation from each other; they form a network of ecosystems that constitute the global system of the biosphere. Students examine how ecosystems are subject to changes that differ in scope, intensity and regularity. They investigate how human activities such as habitat destruction, resource use and disposal of wastes, affect not only the ecological niche that individual species occupy, but the functioning of ecosystems at local and global levels. Students undertake practical investigations into interactions between members of the same and different species and between organisms and their non-living environment. They examine the effect on ecosystems of historical practices, and investigate emerging techniques and technologies that help to monitor and maintain them. Students consider the issues and implications associated with human activities that affect the sustainability of ecosystems.
