Extended Responses for Ecosystems At Risk

Assess the impact of humans on the functioning of TWO ecosystems at risk. (HSC 2013)

Evaluate the impact of both traditional and contemporary management strategies on TWO ecosystems at risk. (HSC 2012)

Discuss the factors that place ecosystems at risk. In your answer, refer to BOTH an ecosystem you have studied AND the ecosystem presented on pages 2 and 3 of the Stimulus Booklet. (HSC 2011) Stimulus Booklet.

‘An ecosystem at risk is both vulnerable and resilient to natural stress and human induced modifications.’ Discuss this statement. (HSC 2010)

Evaluate the importance of ecosystem management and protection. (HSC 2009)

Compare the nature and rate of change that affect the functioning of TWO different ecosystems at risk. (HSC 2008)

Evaluate the impacts of, and responses of people to, environmental change, with reference to at least ONE ecosystem at risk. (HSC 2007)

Evaluate traditional and contemporary ecosystem management strategies in terms of ecological sustainability. (HSC 2006)

Account for the vulnerability and resilience of ecosystems. (HSC 2005)

Describe the spatial patterns and dimensions of ONE case study of an ecosystem at risk, and analyse the negative impacts of human activity on this ecosystem. (HSC 2004)

Justify the importance of ecosystem management and protection. (HSC 2003)

With reference to at least ONE ecosystem you have studied, explain the biophysical interactions which lead to diverse ecosystems and their functioning. (HSC 2002)

Analyse the human impacts affecting the nature and rate of change of TWO ecosystems at risk. (HSC 2001)

Outline how Two ecosystems you have studies could be considered to be at risk. Describe how human activities have affected and altered the nature of both ecosystems.
