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

To determine the most suitable graph for representing animal species diversity, we need to analyze each graph:

1. Graph A (Pie Chart): While it displays proportions, a pie chart is not ideal for comparing species diversity across categories, as it can be difficult to see small differences.

2. Graph B (Bar Chart): This graph effectively shows the number of species in each habitat, allowing for clear comparisons. Each bar represents a habitat, making it easy to visualize and assess diversity quickly.

3. Graph C (Line Graph): This is not suitable, as line graphs are best for showing trends over time rather than categorical comparisons.

4. Graph D (Scatter Plot): Similar to Graph C, scatter plots are more suited for showing relationships between two variables rather than displaying discrete categories such as habitats.

Based on this analysis, Graph B (Bar Chart) is the most suitable graph as it provides a clear and effective comparison of species diversity across the different habitats.
