Final answer:
Species wealth, species richness, and species evenness are measurements used to measure diversity within an ecosystem.
Step-by-step explanation:
Three measurements used to measure diversity within an ecosystem are:
- Species wealth: Species wealth refers to the total number of species recorded for all sites (regional richness) and the average number of species found within sites (local richness).
- Species richness: Species richness is the number of different species in a particular area.
- Species evenness: Species evenness measures the relative abundance of each species within a community.
