The following table lists the global annual values of ecosystem services provided by selected major ecosystems, along with the total area of the globe occupied by each ecosystem type. (Areas are in hectares; a hectare equals 2.5 acres.) Study the table and then answer the questions that follow it.

Which ecosystem has the highest per hectare value? Which one has the highest global total value? Why do you think they are not the same ecosystem for both values? Explain.
