Question

Quizplus · Accepted Answer

The Shannon Index takes into account both the number of species (richness) and the evenness of species abundances. Community B, with a total of five species and a more uneven distribution of individuals among species, will have a higher Shannon Index value than Community A, which has only two species with equal numbers of individuals, indicating greater diversity in Community B.
