Which of the following best describes why aquaculture has grown considerably in several parts of the world?
Aquaculture fisheries provide a larger and more consistent quantity of fish year-round than do wild fisheries
Farmers use various methods of irrigation on crops. Which of the following statements correctly pairs an irrigation method with an advantage or disadvantage?
Flood irrigation is often used in agricultural fields, however, it increases surface erosion and salinization of the soil.
Which of the following is likely to minimize soil erosion?
No-till agriculture

40
This area is likely to have impervious surfaces that increase runoff to streams during a rain event and can contribute to the heat island effect.
A
If the trend in total water withdrawal represented in the graph continues, which of the following is most likely to happen in the future?
Aquifers will be depleted if demand is higher than recharge rate
Based on the data in the graph, which location showed an annual average grain yield in 1991-1993 that was approximately 2.3 times the yield in 1961-1963?
Asia
The cities of Edmorton and Calgary are relatively far north and at high elevation. Which of the following best explains the data presented in their ecological footprints?
Colder average temperatures and longer nights in Edmonton and Calgary lead to high energy usage to heat and light homes.
Which of the following accurately describes a benefit of concentrated animal feeding operations (CAFOs)?
Concentrated animal feeding operations are efficient and relatively low-cost facilities that help keep consumer costs low.
Two branches of a river have different sediment loads. Based on the diagram, which of the following most likely led to the different amount of sediment in tow branches of the river?
Deforestation from clear-cutting
Which of the following best illustrates the concept of the tragedy of the commons?
Depletion of an aquifer by regional farmers
The land on a 100-acre farm is equally suited for grazing cattle and growing corn. Of the following ways of distributing land use, which would produce the greatest number of calories of human consumption?
E
Which of the following best describes a disadvantage of using genetically engineered crops over crops that are not genetically modified?
Genetically engineered plants can decrease the genetic diversity of the crop.
The chart compares the daily water use per person to the price of water in selected countries. Which of the following conclusions can be correctly drawn using only the data in the chart?
Increased water use is generally correlated with lower water prices
Switching from customary large-scale agricultural practices to which of the following is most likely to recue the exposure of farmworkers and nearby residents to toxic chemicals?
Integrated pest management
Which of the following statements best identifies the author's perspective in terms of government funding for future agricultural research?
More funding is continually needed because the agricultural research programs have never been completely financially supported.
Which of the following areas shown on the map of the US has a history of coal deposits and is most likely to have mining operations?
Point B
Based on the diagrams above, which of the following best explains how urban runoff could be decreased?
Replace traditional pavement with more porous pavement to increase ground infiltration.
Which of the following problems is best addressed with contour plowing?
Soil erosion
Which of the following is most likely to occur in a forested region that been recently clear-cut?
The concentration of nitrates in streams running through the region will increase.
Which of the following is the best example of an economic approach to reduce overfishing for a fish species with a declining population?
The federal government sets a catch limit (per person or per boat) for the species and imposes a tax on any extra fish that are caught
Which of the following hypotheses is supported by the trends shown in this graph?
The number of acres burned and the number of wildfires have decreased since 1930 because of more large- scale fire suppression inventions such as prescribed burns.
Which of the following statements best explains the relationship shown on the graph?
The use of glyphosate has selected for herbicide resistance in weed populations.
Many communities experience the tragedy of the commons. One way a local community might regulate a shared and limited resource and reduce the tragedy of the commons is to
divide the resources into parcels and assign them to individuals
Overgrazing of grasslands can lead to reduced range quality. Two of the major effects of overgrazing are
erosion and desertification
Which of the following techniques is a realistic solution for farmers to decrease the amount of fertilizer and sediment runoff in streams?
practices crop rotation
If Student 2 wanted to change his or her footprint to be more similar to that of student 1, which of the following actions would he or she choose based on the data given in table 1?
reducing the amount of meat in his or her diet
Which of the following will be the greatest impact of the development on the local water supplY?
there will be less recharge of groundwater.
One important step that homeowners in the new development can take to protect water quality in Samel Creek would be to
use rain barrels to reduce the flow of storm water into the creek
