The illustration consists of two graphs:

1. A line graph captioned 'Growth of Bacterial Population' is plotted between 'Time in hours' in x-axis ranging from 0 to 6 with an increment of 2 and 'Number of Bacteria' in y-axis ranging from 0 to 300,000 with an increment of 100,000.The graph is exponential. A curve is drawn passing through the coordinates (0 comma 0), (2 comma 0), (4 comma 1000) and (6 comma 250000).
2. A line graph captioned 'Growth of Elephant Population' is plotted between 'Time in years' in x-axis ranging from 0 to 750 with an increment of 250 and 'Number of Elephants' in millions in y-axis ranging from 0 to 20 with an increment of 5. The graph is exponential. The curve is drawn passing through the coordinates (0 comma 0), (250 comma 0.5), (500 comma 1) and (750 comma 20).
