- soybean biodiesel
- cellulosic-based ethanol from switchgrass
- corn-grain ethanol
- pelletized biomass from cellulosic feedstocks
- hybrid poplars
A: corn-grain ethanol

Q: Which of the following is a potential threat to water resources sustainability in the North Central Region?
- increased bioenergy feedstock production on irrigated land
- inefficient bioenergy processing facilities
- production of annual bioenergy crops on former CRP land
- all of the above
A: all of the above

Q: The Earth is known as the Blue Planet because 70 percent of its surface is covered with water; what is the percent of water available on land?
- 30%
- 1.5%
- 2.4%
- 10%
A: 2.4%

Q: Which of the following are not processes in the Water Cycle?
- condensation and precipitation
- production and cultivation
- evaporation and transpiration
- runoff and infiltration
A: production and cultivation

Q: Which of the following describes water that is available for evapotranspiration?
- water accumulated in clouds
- runoff water from rainfall
- water that evaporates from ponds
- water held as soil moisture
A: water held as soil moisture

Q: Which bioenergy crops are expected to provide for the greatest infiltration?
- cultivated corn and soybeans
- poplar and willow
- miscanthus and switchgrass
- all the above will be the same
A: poplar and willow

Q: Which of the following is not true for native, perennial crops used in cellulosic-based bioenergy production?
- vegetation is removed at harvest, leaving roots intact to prevent soil erosion
- expected to require less fertilization and pesticide applications than most row crops
- research on large-scale operations shows positive impacts on water quality
- they are more profitable to grow than row crops for bioenergy
- both b and d
- both c and d
A: both c and d

Q: Ecological Intensification is described as:
- the concept of raising grain yields closer to their genetic potential
- reducing environmental consequences of soil degradation
- increasing yield on currently cultivated lands
- preventing expansion of crop production onto marginal or sensitive lands
- all of the above
A: all of the above

Q: Ecological Intensification relies solely on biotechnology to achieve its desired goals.
- True
- False
A: False

Q: Consumptive use of water for corn-grain ethanol production can be characterized as:
- dominated solely by feedstock production
- zero liquid discharge
- variable across the North Central Region
- consistent in all production facilities, since corn is corn
A: variable across the North Central Region
