Site 1 has a Simpon's Diversity Index of 0.81 and site 2 has 0.43. Choose the correct statement.

• Site 1 is more biodiverse than site 2

• Site 2 is more biodiverse than site 1

• You cannot compare the biodiversity of two different sites

• These numbers are qualitative and therefore more data is required to compare both sites

DOK Level 2: Skill/Concept

A biologist calculates the Simpson's Index of two areas: 0.75 and 0.85. What can be inferred about the biodiversity of these areas?

• Both areas have high biodiversity, but the area with 0.85 has higher biodiversity.

• Both areas have low biodiversity, but the area with 0.85 has slightly higher biodiversity.

• The area with 0.75 has higher biodiversity than the area with 0.85.

• It is impossible to determine biodiversity from Simpson's Index alone.

Interpret the following data to calculate biodiversity: In a survey, 40 species were found in Area X and 30 species in Area Y. Area X had a Simpson's Index of 0.90, and Area Y had an index of 0.85. Which area has higher biodiversity?

• Area X

• Area Y

• Both are equal

• Cannot be determined from the data
