Answer to Question 1

TRUE

Answer to Question 2

The Simpson's Diversity Index measures the likelihood that two individuals drawn from the same community will be of different species. This likelihood is expressed quantitatively as follows:
Simpson's diversity =1 - (proportion of species A)2 -(proportion of species B)2 _ . . . ..

Advantage: To capture the importance of heterogeneity, measures of diversity other than simply the number of species have been proposed.
