A developer owns the property encompassing the three habitats above. By law, one of the habitats must be left intact to satisfy the zoning
laws. The developer works with an environmental engineer to choose which of the habitats should be saved. The environmental engineer
suggests that Site C should be saved. Which of the following choices best justifies this decision?
Site C has greater species richness and species evenness than either Site A or Site B. This will promote the maximum sustainability for future
generations of animals.
Site C is tied with Site A for greatest species richness, but unlike Site A, it has representative species from all 3 of the sites within it.
Site C not only contains the greatest number of species, it also has the greatest genetic diversity within each species.
Site C has more unique species in it than either Site A or…
