In your backyard you overturn a large rock. In the damp soil underneath the rock, you see various insects scurrying for cover: one black spider, five black ants, two brown beetles, and three gray pillbugs. In this community of organisms, species richness is represented by
◦ the ants, since there are more of them than any other organism.
◦ the ants and the spider equally, since they have the greatest number of organisms of the same color.
◦ four different species of organisms.
◦ eleven total organisms.
