The goal of even-aged management of a forest is
- A.
Maintenance of maximum biological diversity.
- B.
Production of high-quality timber.
- C.
A long-term ecologically oriented approach.
- D.
To grow and harvest monoculture forests.
- E.
Multiple use of forest for timber, watershed protection and recreation.
Correct Answer
D. To grow and harvest monoculture forests.Explanation
The goal of even-aged management of a forest is to grow and harvest monoculture forests. This means that the management approach focuses on cultivating and harvesting trees of the same age and species. This allows for efficient timber production, as trees can be harvested at the same time, and it simplifies management practices. However, it may not promote maximum biological diversity as monoculture forests lack the variety of species found in natural forests. It is not a long-term ecologically oriented approach as it may have negative impacts on ecosystem health. Multiple use of the forest for timber, watershed protection, and recreation may not be the primary goal in even-aged management.Rate this question:

High cost of gasoline
- B.
State and local zoning
- C.
Availability of mortgages
- D.
Government loan guarantees to veterans
- E.
Ample land for expansion
Correct Answer
A. High cost of gasolineExplanation
High cost of gasoline is not a factor that leads to urban sprawl because it discourages long commutes and encourages people to live closer to their workplaces. Urban sprawl is typically driven by factors such as state and local zoning regulations that allow for low-density development, the availability of mortgages that make it easier for people to buy homes in suburban areas, government loan guarantees to veterans that facilitate homeownership, and the presence of ample land for expansion on the outskirts of cities.Rate this question:

Which of the following is not appropriate to use in describing a tropical rain forest?
- A.
Humid
- B.
Rich soil
- C.
Stratified
- D.
Diversity
- E.
Rainfall
Correct Answer
B. Rich soilExplanation
A tropical rainforest is characterized by high humidity, stratified layers of vegetation, high species diversity, and abundant rainfall. However, it does not typically have rich soil. The constant rainfall and rapid decomposition of organic matter in the rainforest result in nutrients being quickly absorbed by the plants, leaving the soil relatively poor in nutrients. Therefore, "rich soil" is not an appropriate characteristic to use in describing a tropical rainforest.Rate this question:

The hydrologic cycle is driven primarily by
- A.
Solar energy and gravity.
- B.
Solar energy and the moon.
- C.
Solar energy and the mechanical energy.
- D.
Mechanical and chemical energy.
- E.
Chemical energy and the moon.
Correct Answer
A. Solar energy and gravity.Explanation
The hydrologic cycle, also known as the water cycle, involves the movement of water on Earth through various processes such as evaporation, condensation, and precipitation. Solar energy plays a crucial role in this cycle as it provides the energy needed for evaporation to occur. The heat from the sun causes water to change from a liquid state to a gaseous state, and this water vapor rises into the atmosphere. Gravity then plays a role in the hydrologic cycle by pulling the water vapor back down to Earth as precipitation, which can take the form of rain, snow, or hail. Therefore, solar energy and gravity are the primary driving forces behind the hydrologic cycle.Rate this question:

The fragility of the desert ecosystem is indicated by
- A.
The high growth rate of plants.
- B.
Moderate species diversity.
- C.
Abundant groundwater.
- D.
Long regeneration time from vegetation destruction.
- E.
Having shallow roots.
Correct Answer
D. Long regeneration time from vegetation destruction.Explanation
The fragility of the desert ecosystem is indicated by the long regeneration time from vegetation destruction. This means that when plants in the desert are destroyed, it takes a significant amount of time for them to grow back. This suggests that the ecosystem is not resilient and is easily disrupted by disturbances. The other options, such as high growth rate of plants, moderate species diversity, abundant groundwater, and having shallow roots, do not necessarily indicate fragility as they can be present in a healthy and robust ecosystem.Rate this question:

In alley cropping,
- A.
Crops are planted between hedgerows of trees or shrubs that are used for fruits or fuelwood.
- B.
Terrace are built to prevent swift water runoff.
- C.
Plowing runs across slopes.
- D.
Special tillers are used so the topsoil is not disturbed.
- E.
A row crops alternates in strips with another row crop.
Correct Answer
A. Crops are planted between hedgerows of trees or shrubs that are used for fruits or fuelwood.Explanation
In alley cropping, crops are planted between hedgerows of trees or shrubs that are used for fruits or fuelwood. This practice allows for the simultaneous cultivation of annual crops and the production of trees or shrubs for additional benefits such as providing fruits or fuelwood. The trees or shrubs act as windbreaks, provide shade, and help in reducing soil erosion. This system promotes sustainable agriculture by maximizing land use efficiency and diversifying income sources for farmers.Rate this question:

To help protect the food supply and fight pests responsibly, individuals can
- A.
Use larger amounts of pesticides when necessary.
- B.
Dispose of unused pesticide where it will continue to kill pests.
- C.
Allow native plants to cover most of their property.
- D.
Use powerful synthetic to pesticides.
- E.
Help eradicate all pests everywhere.
Correct Answer
C. Allow native plants to cover most of their property.Explanation
Allowing native plants to cover most of their property can help protect the food supply and fight pests responsibly. Native plants provide habitat and food sources for beneficial insects and birds that can naturally control pest populations. They also help to maintain biodiversity and ecological balance, reducing the need for pesticides. By encouraging the growth of native plants, individuals can create a more sustainable and environmentally-friendly approach to pest management.Rate this question:

Characteristics that make amphibians particularly sensitive to pollution include
- A.
Living part of their life cycle in water and part on land.
- B.
Soft, permeable skin.
- C.
Sensitivity to ultraviolet radiation.
- D.
All of these answers.
- E.
None of these answers.
Correct Answer
D. All of these answers.Explanation
Amphibians are particularly sensitive to pollution due to a combination of factors. Firstly, they have a life cycle that involves living in both water and on land, making them vulnerable to pollutants in both environments. Additionally, amphibians have soft and permeable skin, which allows for the absorption of pollutants from the surrounding water or soil. Lastly, they are also sensitive to ultraviolet radiation, which can be intensified by pollution. Therefore, all of these characteristics contribute to the heightened sensitivity of amphibians to pollution.Rate this question:

Microclimates are least likely to be produced by
- A.
Mountains.
- B.
Bodies of water.
- C.
Cities.
- D.
Flat plains.
- E.
Sand dunes.
Correct Answer
D. Flat plains.Explanation
Microclimates are small-scale variations in weather conditions within a larger region. They are influenced by various factors such as topography, vegetation, and bodies of water. Mountains, bodies of water, cities, and sand dunes can all create microclimates due to their unique characteristics. However, flat plains are less likely to produce microclimates because they lack significant variations in elevation or other features that can influence weather patterns. Therefore, flat plains are the least likely to create microclimates.Rate this question:

The organisms that are classified as primary consumers are the
- A.
Detritivores.
- B.
Omnivores.
- C.
Carnivores.
- D.
Decomposers.
- E.
Herbivores.
Correct Answer
E. Herbivores.Explanation
The organisms that are classified as primary consumers are herbivores. Herbivores are organisms that primarily feed on plants or plant material. They obtain their energy by consuming producers, such as plants, and are considered the first level of consumers in a food chain or food web. They play a crucial role in transferring energy from plants to higher trophic levels in an ecosystem. Detritivores, omnivores, carnivores, and decomposers are not classified as primary consumers as they have different feeding habits and occupy different trophic levels in the food chain.Rate this question:
