a)
Energy
b)
Minerals
c)
Fresh water
d)
Arable (farmable) land
4.
According to one source, approximately 70% of the world's freshwater is currently used by agriculture. What problem is at the root of this stress on the world's freshwater sources?
a)
Exponential human population growth
b)
Lack of funding for agriculture programs
c)
Development of genetically modified crops
d)
Increasing numbers of pathogens in aquatic ecosystems
5.
What is the relationship between biodiversity of life on Earth and the distribution of sunlight on Earth's land areas?
a)
Earth's biodiversity is equal everywhere that receives sunlight
b)
Biodiversity is directly related to the amount of sunlight received by an ecosystem
c)
Earth's biodiversity is not related to the amount of sunlight the ecosystem recieves
d)
Biodiversity is inversely proportional to the amount of sunlight received by an ecosystem
6.
When plants receive solar energy and photosynthesize, which form of energy is used for storage?
a)
Heat energy
b)
Light energy
c)
Nuclear energy
d)
Chemical energy
7.
What is the most probable effect agriculture has on river water within the floodplain of the river?
a)
The river becomes clearer
b)
Flooding becomes less of a problem
c)
Nitrogen content of the river water is reduced
d)
Sediment content of river water is increased
8.
What would be the most sustainable strategy in an agricultural area that is being depleted of irrigation water sources?
a)
plowing deeper into the soil
b)
increasing the rate of irrigation
c)
drilling deeper wells for irrigation
d)
planting crops with deeper root systems
9.
How does deforestation affect global climate?
a)
It has no effect on global climate
b)
It increases global warming because less carbon dioxide is abosrbed
c)
It decreases global warming because more carbon dioxide is absorbed
d)
It increases global warming due to high sunlight reflection from bare ground
10.
North Carolina regulations prevent the destruction of wetlands immediately adjacent to large bodies of water. What is one reason it is important to protect these weland areas from development?
a)
Wetland areas contain naturally toxic water and should not be disturbed
b)
Wetland areas that lose vegetation reduce the evaporation rate and raise the water table
c)
Wetland areas act as buffers, filtering out non-point source pollutants such as nitrogen and phosphorous containing substances
d)
Wetland areas that are developed reduce sedimentation, preventing the development of river deltas
11.
North Carolina lost over 50% of its original wetlands to development, primarily for agriculture. How has this most likely affected water quality?
a)
by increasing run off pollutant consentrations
b)
by decreasing the need for clean water
c)
by decreasing sedimentation
d)
by increasing dissolved oxygen
12.
Researchers estimate that in 1850, the amount of fresh water available per person was 43,000 cubic meters annually. By 1990, the water available per person had dropped to 9,000 cubic meters annually. What is primarily responsible for this change in availability of fresh water?
a)
threats to biodiversity
b)
changes in rainfall pH
c)
global population growth
d)
development of desalination process
13.

around 60
c)
around 80
d)

a)
It has no effect on the ecosystem
b)
It benefits all other organisms in the ecosystem
c)
It allows other species to affect the ecosystem significantly
d)
It stabilizes the population of all other organisms in an ecosystem
15.
Many farm operations are embracing the local food movement by only purchasing livestock feed and fertilizers that originate within a 100-mile radius and only distributing their products within a 400-mile radius.
What impact could widespread adoption of the local food movement have on the environment?
What impact could widespread adoption of the local food movement have on the environment?
a)
Loss of genetic diversity due to cross-pollination
b)
Less available groundwater as a result of irrigation
c)
Cleaner air as a result of decreased transportation needs
d)
Nutrient-depleted soils as a result of growing local varieties
