Biodiversity and Conservation Questions
Which of the following is NOT a potential benefit of reintroduction efforts?
-
Increased genetic diversity.
-
Improved ecosystem function.
-
Reduced risk of extinction.
-
Increased tourism revenue.
D
Correct answer
Explanation
While increased genetic diversity, improved ecosystem function, and reduced risk of extinction are all potential benefits of reintroduction efforts, increased tourism revenue is not.
Which of the following is NOT a key factor to consider when selecting a reintroduction site?

What is the role of revegetation in the reclamation of mining and quarrying sites?
-
To provide cover for the soil
-
To help stabilize the soil
-
To improve soil fertility
-
All of the above
D
Correct answer
Explanation
Revegetation plays an important role in the reclamation of mining and quarrying sites. It provides cover for the soil, which helps to reduce erosion and improve soil moisture retention. Revegetation also helps to stabilize the soil, which can help to prevent landslides and other problems. Additionally, revegetation can help to improve soil fertility by adding organic matter to the soil.
