Worked Solution & Example Answer:Analyse the data shown in Figure 11 and Figure 12 - AQA - A-Level Geography - Question 6 - 2018 - Paper 1
Step 1
Figure 11 Analysis
Answer
Figure 11 illustrates a stark decline in top marine predators across various regions, with the Baltic Sea showing a notable loss of around 11%. The median decline in these areas hovers around 4.5 - 5%, indicating widespread concern regarding marine health. Notably, the Mediterranean Sea is an exception, possibly indicating a more stable predator population.
Step 2
Figure 12 Analysis
Answer
Figure 12 presents data on the proportion of assessed fish stocks within and outside safe biological limits in 2008. The North Sea and North East Atlantic report a high number of assessed stocks, but they still face overfishing, with only 5% classified as sustainable. Conversely, regions like the Gulf of Lions appear healthier, with 11 out of 15 stocks assessed as sustainable. This discrepancy indicates a need for focused conservation efforts in overfished regions.
Step 3
Connection Between Figures
Answer
The data in Figures 11 and 12 interrelate to emphasize the broader issue of marine conservation. The decline in top marine predators highlighted in Figure 11 aligns with the overfishing data presented in Figure 12, showcasing a concerning trend that highlights the urgent need for management strategies to protect marine biodiversity.
