A group of four students set out to determine the animal species diversity over an area of one hectare in each of five different habitats - HSC - SSCE Biology - Question 8 - 2019 - Paper 1

Among the graphs presented, Graph B is the most suitable for representing animal species diversity. This is because it uses a bar chart to clearly depict the number of species in each habitat, allowing for straightforward comparison. The height of each bar corresponds directly to the number of species, providing an immediate visual understanding of the diversity across the different habitats. On the other hand, Graph A uses a pie chart which may not effectively convey the information regarding diversity, as it is better suited for representing proportions rather than absolute values. Graph C and D both present line and shaded area graphs, respectively, which may not be ideal for categorical data like species counts across discrete habitats.
