Biodiversity Conservation And Wild Life Question 43
Question: Human activities such as clear-cutting and road building often create edges between areas of different habitat. Edges created by human activities:
Options:
A) are usually more abrupt than natural boundaries between habitats.
B) may have their own species not present in adjacent habitats.
C) may be dominated by relatively few species.
D) All of the above
Show Answer
Answer:
Correct Answer: D
Solution:
The correct answer is D) All of the above.
Here’s why:
A) are usually more abrupt than natural boundaries between habitats. Human activities such as clear-cutting and road building often create abrupt edges between different habitats. These edges are typically more sudden and distinct than natural boundaries, which can be more gradual and allow for a smoother transition between different habitats.
B) may have their own species not present in adjacent habitats. Edges created by human activities can sometimes become a unique habitat in their own right, hosting species that are not found in the adjacent habitats. This is known as the “edge effect,” where certain species thrive at the boundary between habitats.
C) may be dominated by relatively few species. The species that inhabit these human-created edges are often those that are particularly adaptable and can thrive in a variety of conditions. As a result, these edge habitats may be dominated by a relatively small number of species, reducing biodiversity.
So, all of the above statements are correct, making option D the correct answer. Human-created edges can have significant impacts on local ecosystems, affecting the distribution and diversity of species. This is a key consideration in conservation efforts and land-use planning.
