Scientists counted the numbers of five different animals in the river at sites A and B. Table 2 shows the results. Complete Figure 7. You should use data from Table 2 for the sludge worm and the bloodworm.

The task is to plot the data from Table 2 onto the bar chart in Figure 7 for two animals. - **Sludge worm:** Table 2 shows 80 animals at Site A and 2 at Site B. On the chart, under "Sludge worm", the bar for Site A (white) should be drawn to a height of 80. The bar for Site B (grey) should be drawn to a height of 2. - **Bloodworm:** Table 2 shows 36 animals at Site A and 8 at Site B. On the chart, under "Bloodworm", the bar for Site A (white) should be drawn to a height of 36. The bar for Site B (grey) should be drawn to a height of 8.
