A farming region experiences heavy fertilizer runoff into a lake. Which sequence is the most likely environmental consequence?
- A
Increased soil organic matter and improved water clarity
- B
Lower evaporation and higher groundwater recharge
- C
Algal blooms followed by oxygen depletion
- D
Reduced plant growth because nutrients are removed from the water
Which description best represents agribusiness?
- A
Only farms that grow crops for household use
- B
Only government agencies that regulate food production
- C
Only restaurants and grocery stores that sell prepared food
- D
Businesses and activities connected to agricultural inputs, production, processing, distribution, retail, and food services
Which statements accurately describe the Green Revolution? Select all that apply.
- A
Its improved varieties generally required supporting inputs such as irrigation and fertilizer to achieve high yields.
- B
It eliminated the need for government policies and infrastructure.
- C
Its benefits were uneven where farmers lacked water, capital, roads, or research focused on local crops.
- D
Intensive input use could contribute to groundwater depletion, soil degradation, pesticide exposure, and water pollution.
Which practices or claims are consistent with sustainable agriculture as described in the material? Select all that apply.
- A
Crop rotation can interrupt pest cycles and improve soil fertility.
- B
Cover cropping can protect soil and increase organic matter.
- C
Monocropping across large areas generally increases habitat diversity and reduces pest vulnerability.
- D
Efficient irrigation methods can reduce water loss.
True or false: A region can produce a large quantity of food while some households there remain food insecure.
- A
True
- B
False
True or false: Drip irrigation is automatically a sustainable solution in every agricultural setting because it can conserve water.
- A
True
- B
False
According to the material, approximately what percentage of total human-caused emissions came from global agrifood systems in 2022? Enter the value in percentage points; the fixed unit is %.
What single term describes the process in which excess nitrogen and phosphorus promote algal blooms and subsequent oxygen depletion in water?
Complete the agricultural value chain: inputs → farming → storage → → transportation → wholesale → or food service → consumption.
In a dry irrigated region, evaporation leaves salts behind in the soil and crop productivity declines. This process is called .
A farming cooperative is considering installing a new irrigation system to stabilize yields during increasingly variable rainfall. Evaluate whether the project is sustainable. Discuss likely benefits, environmental risks, economic and social considerations, and conditions or management practices that would improve its sustainability.
Which nutrient, beginning with the letter N, is one of the three nutrients specifically identified in the material as being supplied by synthetic fertilizers?
Which situation best illustrates agricultural diffusion?
- A
The replacement of all traditional farming with mechanized farming
- B
The spread of crops, livestock, farming practices, or technologies between places
- C
The conversion of farmland into protected wilderness
- D
The measurement of farm output per unit of labor
Why did Green Revolution technologies increase yields most effectively in places with adequate water, inputs, research, and infrastructure?
- A
Introducing a new crop variety without changing farm management
- B
Replacing food crops with forests to increase biodiversity
- C
Combining improved crop varieties with irrigation, fertilizers, research, and supportive infrastructure
- D
Reducing all agricultural inputs in order to eliminate environmental impacts
A farmer uses soil sensors and GPS-guided equipment to apply fertilizer at different rates across one field. Which agricultural technology is being used?
- A
Applying different amounts of seed, fertilizer, or water to different parts of a field based on data
- B
Using only hand tools so that no farm machinery is needed
- C
Growing one crop continuously across the entire farm
- D
Moving a farm to a region with more favorable climate conditions
Which sequence most accurately represents the movement of a harvested crop through an agricultural value chain?
- A
Retailing → farming → processing → input supply
- B
Processing → input supply → farming → consumption
- C
Consumption → farming → transportation → storage
- D
Farming → storage → processing → transportation → wholesale → retail
Which statement best applies the material's multidimensional definition of food security?
- A
Food security depends only on the total amount of food produced in a region.
- B
High regional production guarantees that every household can obtain a nutritious diet.
- C
A region may produce substantial food while poverty, conflict, unequal distribution, or high prices leave some households food insecure.
- D
Food insecurity occurs only when a region produces no food at all.
True or false: A farming practice can be considered sustainable solely because it increases crop yields, even if it degrades soil and is not economically viable.
- A
True
- B
False
According to the material, approximately what percentage of total human-caused greenhouse-gas emissions came from global agrifood systems in 2022? Enter the percentage-point value to one decimal place.
