Land and Water Use

An integrated pest management approach to pest control emphasizes which of the following?

• Eradication of the pest problem
• Reliance on spraying broad-spectrum pesticides
• Reduction of crop damage to an economically tolerable level
• Using plant monocultures to simplify spraying

In a typical forest ecosystem, dead trees and fallen trees are most important because of their role in which of the following?

• providing a valuable resource of timber
• providing habitat for wildlife
• removing carbon dioxide from the air
• contributing to soil erosion

When a rain forest is slashed and burned, the local concentration of carbon dioxide in the atmosphere increases.  This is primarily due to:

• oxidation of carbon compounds
• cellular respiration of rain forest plants
• erosion of exposed soil
• CO₂ being released by anaerobic bacteria in the soil

In which of the soil horizons would you find nitrification taking place?

• o
• a
• e
• b

Which of the soil horizons is closest to bedrock?

• o
• a
• b
• c

Which soil type would have the highest permeability?

• One with high amounts of sand
• One with high amounts of silt
• One with high amounts of clay
• Loam

The ability of a soil to deliver Mg⁺², Ca⁺², and K⁺  to the roots of a plant is known as:

• Base Saturation
• Cation Exchange Capacity
• pH buffer system
• Urban Sprawl

A deficiency in this will lead to blindness and then death.

• Vitamin A
• Iodine
• Iron
• Protein

A deficiency in this leads to goiter and then irreversible brain damage

• Vitamin A
• Iodine
• Iron
• Protein

Organic Farming bans all of the following EXCEPT

• Pesticides
• GMOs
• Synthetic Fertilizers
• Equipment that uses fossil fuels
