Two savanna communities both contain 15 plant species. In community A, each of the 15 species is represented by 20 individuals. In community B, 10 of the species are each represented by 12 individuals; the remaining 5 species are each represented by 3 individuals. Which statement best describes the two communities?

• Community A has the same biodiversity as community B
• Both communities have the same species evenness
• Community B has a higher species richness
• Community A has higher species evenness
