Question
The table shows solid domestic waste data for the state of Victoria, Australia in 2006–2007.
[Source: adapted from National Waste Overview 2009 © Copyright vests in the Commonwealth of Australia and each Australian State and Territory]
State one type of solid domestic waste management strategy.
Outline one advantage and one disadvantage of the strategy named in 1(a)(i).
From the data, calculate the proportion of paper and of food waste as a percentage of the total.
Enter these two values in the table above.
Complete the following bar chart by using the data calculated in (b)(i). Label the chart correctly.
Define the term carrying capacity.
Outline why it is difficult to measure carrying capacity for a human population.

Examiners report
The majority of candidates correctly identified a solid waste management strategy and associated advantage and disadvantage.
The majority of candidates correctly identified a solid waste management strategy and associated advantage and disadvantage.
Most candidates correctly calculated the two percentages required and were able to draw the two missing bars from the bar chart but many did not label the x and y axis.
Most candidates correctly calculated the two percentages required and were able to draw the two missing bars from the bar chart but many did not label the x and y axis.
Often the definition for carrying capacity was incomplete with concepts of ‘maximum number of a species’ and/or ‘sustainability’ missing.
Many candidates incorrectly focused on how population size varies rather than on aspects that determine resource use.
