6
Which best describes the relationship between carrying capacity and Earth's resources?
Population below carrying capacity decreases freshwater.
Population above carrying capacity decreases resources
Population above carrying capacity increases plant products.
Population below carrying capacity increases disease
7
Which could most likely have a lasting negative impact on the biodiversity of an area?
selective cutting
clear-cutting
a reduction in the use of fertilizers
an increase in plant populations
8
In which way could the average increase in global temperature influence Earth?
increasing the formation of sea ice within polar regions
decreasing erosion within coastal ecosystems
decreasing periods of drought in all water systems
increasing amounts of flooding because of rising sea levels
9
Why would local government vote against large-scale development of buildings & roads in an area
It could decrease acid rain production in the area.
It could form heat islands which impact the microclimate.
