Industrial Agriculture has many benefits.  Which of the following is NOT a benefit associated with industrial agriculture?

• The ratio of energy input to calorie output is low.
• Larger food production per hectare.
• Monoculture can be more efficient.
• Economy of scale can make the food less expensive.

Typically, most of the energy subsidies in modern agriculture are in the form of

• solar power.
• hydroelectric power.
• nuclear power.
• fossil fuels.

Synthetic fertilizers have many advantages over traditional "organic" animal waste fertilizers.  These include all of the following EXCEPT

• ease of application.
• highly adjustable nutrient content.
• bioavailability of nutrients.
• lack of nutrient runoff problems.

Monocropping has a number of disadvantages.  These include all of the following EXCEPT

• erosion due to exposure of large areas of soil during planting.
• Nutrition and pesticide needs should be similar throughout a single crop.
• Pests are ore likely to attack a monocrop due to the high concentration.
• Loss of habitat for natural pest predators.

After many years of applying the selective pesticides provironex, a farmer notices that the applications seem less effective.  This is likely due to

• the fact that provironex is fat soluble and has been bioaccumulating.
• provironex is selective, so other pests are filling the niche from the exterminated ones.
• provironex is persistent, and the farmer should apply less for better results.
• the target species has begun to evolve resistance.

Scientists have inserted a gene for the production of vitamin A into rice.  This practice of changing the genetic structure of agricultural products to improve desirable traits is known as

• Genetic Engineering.
• Transmodification.
• Selective Breeding.
• Natural Selection.

Which areas of the world are most susceptible to desertification?

• Humid Equitorial Regions
• Temporal Chaparral
• Areas adjacent to the Poles.
• Areas adjacent to Existing Deserts.

IPM is likely to use all of the following techniques EXCEPT

• intercropping.
• planting herbicide-resistant crops.
• habitat creation for pest predators.
• increased use of traditional pesticides.

IPM is especially successful in developing countries because 

• the availability of high quality pesticides in developing countries is spotty at best.
• high-input industrial farming is not feasible because farmers lack financial resources.
• IPM resembles traditional farming techniques so closely.
• developed nations often offer subsidies to farmers using IPM techniques.
