Question

Which of the following is not a concern regarding habitat fragmentation?
A. Habitats can change type.
B. Habitats can be too small to support some species.
C. It reduces the dispersal ability of some animals.
D. It creates a large amount of vulnerable edge habitat.

Answer 1

Hint: During the process of habitat fragmentation, a large area of habitat gets divided into several smaller patches with smaller total areas that are isolated from one another by a matrix of habitats that is not the original habitat.

Complete step-by-step answer:

Population fragmentation and ecosystem deterioration are brought on by the development of discontinuities (habitat fragmentation) in an organism's preferred environment.

When portions of habitat are destroyed, smaller, disconnected sections are left behind, leading to fragmentation. Although fire or volcanic eruptions might cause this naturally, human activity is typically at blame. A straightforward illustration is building a road through a forest. 16

Geological processes that gradually change the physical environment's architecture and human action, such as land conversion, which can change the environment much more quickly and result in the extinction of many species, are both sources of habitat fragmentation. More specifically, the process of habitat fragmentation involves the division of huge, continuous habitats into smaller, isolated habitat patches.

Five distinct phenomena are included in the phrase "habitat fragmentation":

- Reduction in the habitat's overall size
- Reduction in the interior-to-edge ratio
- Separation of a single habitat fragment from additional habitat areas
- Dividing a large habitat area into multiple smaller patches
- Reduction in the average size of each habitat patch

Therefore, option A is the correct answer.

Note: As a reaction to habitat fragmentation, the following four steps must be implemented in priority order:
-Preserve the current, top-notch animal habitat.
-Maintain and upgrade deteriorating green space.
-Restore devastated sites with special significance (such as wetlands)
-Increase the inter-site permeability of land use.
