Provided uneaten meat for scavengers such as ravens, bald eagles, ermines and foxes
Correct Answer
C. Decreased big game populationsExplanation
The correct answer is "decreased big game populations." The text mentions that wolves provide ecological services such as culling herds of bison, elk, caribou, and mule deer, keeping down coyote populations, and providing uneaten meat for scavengers. However, it does not mention that wolves decrease big game populations.Rate this question:

This power of eminent domain allows the government to force a citizen to sell their property if it is needed for a public good, such as building roads or public infrastructure.Rate this question:

Read 23-2. ______________ are stands of trees resulting from secondary ecologal succession after the trees in an areas have been removed by human activities or natural forces such as hurricanes or fires.
- A.
Frontier forests
- B.
Second-growth forests
- C.
Old-growth forests
- D.
Virgin forests
- E.
Both a and c are correct
Correct Answer
B. Second-growth forestsExplanation
The correct answer is "second-growth forests". This is because second-growth forests refer to stands of trees that have regrown after the original trees were removed due to human activities or natural forces. These forests are a result of secondary ecological succession, which occurs when a new community of plants and animals replaces an existing one after a disturbance. This can include disturbances like hurricanes or fires. The other options, such as frontier forests, old-growth forests, and virgin forests, do not accurately describe the regrowth process after disturbance.Rate this question:

Read 23-2. industrial forestry includes planting monocultures that are cut every 25-30 years.in the United States. In tropical countires, where trees can grow more rapidly the rotation cycle can be _____ years
- A.
2-3
- B.
15-20
- C.
40-50
- D.
6-10
Correct Answer
D. 6-10Explanation
In tropical countries, where trees can grow more rapidly, the rotation cycle for industrial forestry can be shorter, typically ranging from 6 to 10 years. This is because the favorable climate and conditions in tropical regions allow trees to grow faster compared to other regions. Therefore, the shorter rotation cycle allows for more frequent harvesting and replanting of monocultures in order to maximize timber production.Rate this question:

Read - HOW TREES ARE HARVESTED. What type of harvesting removes all mature trees in two or typically three cuttings over a period of about 10 years?
- A.
Clear cutting
- B.
Seed-tree cutting
- C.
Selective cutting
- D.
Shelterwood cutting
- E.
High-grading
Correct Answer
D. Shelterwood cuttingExplanation
Shelterwood cutting is a type of harvesting that removes all mature trees in two or typically three cuttings over a period of about 10 years. This method involves gradually removing the older trees in a forest while leaving behind a small number of seed-producing trees to regenerate the forest. The remaining trees provide shelter and shade for the new seedlings, ensuring their successful growth and establishment. This approach allows for sustainable timber production while also promoting the regeneration and biodiversity of the forest ecosystem.Rate this question:

What type of forest fire usually burns undergrowth and leaf litter on a forest floor and can help prevent more destructive fires.
- A.
Crown
- B.
Surface
- C.
Subsurface
- D.
Litter
- E.
Detrimental
Correct Answer
B. SurfaceExplanation
Surface fires are the type of forest fires that usually burn undergrowth and leaf litter on the forest floor. These fires help prevent more destructive fires by clearing out the excess fuel load and reducing the chances of a larger, more intense fire. Surface fires are typically low-intensity fires that do not reach the canopy or crown of the trees, making them less detrimental to the overall forest ecosystem.Rate this question:

Read 23-7. There are four basic strategies to ecological restoration. Which of the following would be exemplified by removing PCB's from Lake Worth.
- A.
Restoration
- B.
Rehabilitation
- C.
Replacement
- D.
Creating artifical ecosystems
- E.
None of the above
Correct Answer
B. RehabilitationExplanation
The correct answer is rehabilitation. This is because removing PCB's from Lake Worth is an example of restoring the lake to its original, healthy state. Rehabilitation involves repairing or improving an ecosystem to its previous condition, rather than creating completely new ecosystems or replacing them with artificial ones.Rate this question:

Traingle
- B.
Square
- C.
Rectangle
- D.
Circle
- E.
All work equally well
Correct Answer
D. CircleExplanation
A circle is the most ideal shape when creating a nature reserve because it has no corners or edges, allowing for a continuous and uninterrupted flow of natural habitats. This shape provides the most efficient use of space and ensures that there are no areas that are difficult to access or maintain. Additionally, a circular shape promotes a sense of harmony and balance within the reserve, creating a more aesthetically pleasing environment for both wildlife and visitors.Rate this question:

Read 23-6. Gap Analysis is a new scientific method that has been developed to determine how adequately native plant and animals species and natural communitites are protected by existing netweorks of nature preserves. Which of the following is not a step in Gap Analysis
- A.
Combining existing vegetation data and reomte-sensing dats to produce computerized GIS maps
- B.
Superimpose the species distribution maps onto the GIS maps of existing protected ares t determine uportected areas or gaps with very high species diversity or pockets of rare species that are not protected
- C.
Using bioinformatics to show populations size of a threatened species
Correct Answer
C. Using bioinformatics to show populations size of a threatened speciesExplanation
The correct answer is "using bioinformatics to show population size of a threatened species." This step is not mentioned in the given passage about Gap Analysis. The passage only discusses combining vegetation and remote-sensing data to produce GIS maps and superimposing species distribution maps onto existing protected areas to identify unprotected areas or gaps with high species diversity or rare species. The use of bioinformatics to show population size is not mentioned as a step in Gap Analysis.Rate this question:
