A researcher collects data on plant species composition in two habitats (P and Q) by using 10 quadrats each in both habitats. She calculates the average a-diversity and the 13-diversity of each habitat from this data (shown below). Which of the following can be inferred about these habitats? 

A) Q has greater total diversity (γ) and more heterogeneous than P

B) Q has lower total diversity (γ) and less heterogeneous than P

C) P has lower total diversity (γ) and more heterogeneous than Q

D) P has greater total diversity (γ) and more heterogeneous than Q
