Land & Water Use
What is a potential ecological consequence of clearing forests for agricultural expansion?
Reduction in pesticide use as a result of larger monoculture fields.
Increased carbon sequestration due to new plant growth.
Loss of habitat leading to decreased biodiversity.
Enhanced nitrogen fixation by an increase in legume planting.
What is a primary ecological benefit of crop rotation in sustainable agriculture?
It disrupts the life cycles of pests specific to certain crops.
It significantly increases short-term crop yield per hectare.
It allows for continuous monoculture without loss of biodiversity.
It enhances genetic modification transmission between crops.
Which factor would most likely contribute directly towards creating dead zones in coastal waters?
Significant reduction in industrial discharges resulting entirely from improved pollution control technologies solely.
Increased nutrient runoff from heavily fertilized agricultural fields.
Decrease in phytoplankton blooms due largely towards lower sea surface temperatures only.

In considering water conservation in agriculture, what is a potential drawback of using drip irrigation systems over traditional flood irrigation methods?
Higher initial cost and maintenance requirements.
Increased salinization of topsoil from excess water application.
Greater loss of water through evaporation.
Less precise water delivery to plant roots.
Which policy has been most effective in reducing the runoff of agricultural fertilizers into freshwater systems?
Introduction of genetically modified crops to increase yield
Implementation of buffer zones around rivers and streams
Subsidies for organic farming practices
Mandating minimum tillage across all farms
What is a potential unintended consequence of using genetically modified crops that produce their own insecticide?
Lowered production costs due to reduced pesticide applications.
Development of pesticide-resistant insect pests.
Decreased reliance on chemical pesticides for farmers.
Improved nutritional content of the crops produced.
In which way does conventional tilling contribute negatively to environmental impacts compared with no-till methods?
Improved air quality
Decrease herbicide usage
Increase water holding capacity
Increased soil erosion

Which method would most effectively reduce water consumption on a large-scale commercial farm?
Flood irrigation covering fields with thin layers of water.
Drip irrigation systems that deliver water directly to plant roots.
Overhead sprinkler systems spraying large areas simultaneously.
Center pivot irrigation rotating around a central pivot point watering crops.
Which agricultural method would most effectively minimize soil degradation while maximizing crop yield in a region with steep slopes?
Terracing, to create flat areas that reduce runoff and soil erosion.
Overgrazing by livestock, which can lead to compacted soil and increased erosion.
Monoculture planting, where only one type of crop is cultivated over a large area.
Conventional tillage, which involves turning the soil to prepare for new planting.
How does no-till farming potentially decrease an intentional negative impact on soils compared with conventional tillage methods?
Reduces erosion by leaving crop residue on fields.
Decreases biological diversity through compaction layers formation.
Increases nutrient leaching through more frequent irrigation.
Enhances decomposition rates by exposing more organic matter.
