Question 10

A group of ecologists investigated the biodiversity of butterflies in three different ecosystems: ancient woodland, organic farmland, and urban parkland. During the study, they collected specimens of various species, including Pieris brassicae\textit{Pieris brassicae}Pieris brassicae, Pieris rapae\textit{Pieris rapae}Pieris rapae, and Vanessa cardui\textit{Vanessa cardui}Vanessa cardui.

1.

State what is meant by the term 'species richness'.

[1]
2.

Explain what the scientific names of Pieris brassicae\textit{Pieris brassicae}Pieris brassicae, Pieris rapae\textit{Pieris rapae}Pieris rapae, and Vanessa cardui\textit{Vanessa cardui}Vanessa cardui suggest about the evolutionary relationships between these three butterfly species.

[2]
3.

The ecologists decided to calculate the index of diversity for each ecosystem. Explain why measuring the index of diversity is more useful than measuring species richness alone.
