The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services published a report in 2019 that described several negative effects that humans have had
on biodiversity and ecosystem services. They highlighted and ranked five drivers of these negative effects. Which of the following has had the greatest overall impact on
biodiversity and ecosystem services?
A. Pollution
B. Direct exploitation of organisms
C. Invasive species
D. Climate change
E. Changes in land use and sea use

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…

- What is the importance of endemic hotspots to biodiversity conservation? A. Endemic hotspots contain many species found nowhere else, so the conservation of a small amount of area will protect many species. B. Endemic hotspots have the highest species diversity, so their conservation will protect the most species. C. Endemic hotspots are those that contain species vital to human existence, ssuch as medicinal species, and therefore humans rely on these areas the most. D. Endemic hotspots are where speciation rates are thegreatest, so the conservation of those areas will likely lead to the formation of many species in the future. E. Endemic hotspots have very low ecosystem stability, therefore require more protections to avoid extiction.arrow_forwardHabitat fragmentation can reduce biodiversity by a. introducing more native species into a habitat b. sterilizing for pollution control C. decreasing human use of natural resources d. eliminating vast tracts of forests e. withdrawing an essential resource from native speciesarrow_forwardWhich of the following is not true of a population of largepredators in a small reserve?a.
