Question
Samson and Dorothy surveyed two islands, ‘A’ and ‘B’. They recorded the relevant data in the following format in their research folder:
| Parameter | Island A | Island B | |
| (a) | Area (A) | 45 × 103 Km2 | 12 × 105 Km2 |
| (b) | Regression co-efficient (Z) | 1 | 1 |
| (c) | Y-intercept | 20 | 10 |
- Derive the species-richness for each island.
- Which island exhibits greater biodiversity? Support your answer with a reason.

Solution
- S = CAZ
Island 'A' Island 'B' Sa = 20 × (45 × 103)1 Sb = 10 × (12 × 105)1 1 mark Sa = 900 × 103 Sb = 120 × 105 1 mark - Sb > Sa, therefore, species richness of Island ‘B’ is greater than that of Island ‘A’, because Island B has optimum environmental conditions, temperature, and higher productivity.
