Question

Human activities such as clear-cutting and road building often create edges between areas of different habitats. Edges created by human activities:
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

Answer 1

Hint: Habitat fragmentation is the disruption to the Associate in Nursing organism's natural environment, separating it into smaller disjointed items. These erstwhile contiguous habitats become separated, inflicting a decrease in size of natural habitats, smaller area for acquisition of resources, and isolation of teams at intervals a population.

Complete step by step solution:
Human activities like land conversion, also as slower geologic processes resulting in changes within the physical surroundings, are the 2 leading causes of environment fragmentation.
Perforation and dissection typically occur throughout the initial stages of development. As an example, clearing undeveloped land to make a home (i.e., perforation) or road (i.e., dissection) disrupts the otherwise continuous environment. perennial environment perforation or dissection, or a mixture of each, creates an Associate in Nursing more and more disconnected environment - (i.e., fragmentation).
The sides of fragmented habitats are significantly prone to environmental disturbances, like severe weather. This can occur naturally, as a results of fireplace or volcanic eruptions, however is generally thanks to act

Small fragments support less diversity because: 1) edge effects produce environment instability, 2) some species need an out sized environment, and 3) little, isolated populations are unsustainable long run.
Habitat fragmentation studies aim to know its effects on diversity and verify applicable responses to cut back its damaging effects.

Hence, option D is correct.

Note:
Organisms on one facet are isolated and should lack nutrients and different necessary necessities for his or her species. This could result in starvation, death, and unfortunate road accidents as organisms decide to cross into antecedent joined habitats.
