Vedclass · Answer

(A) Habitat destruction and fragmentation are the primary causes of biodiversity loss.When large habitats are fragmented into smaller patches,the total perimeter (edge) of the habitat increases relative to its area.This phenomenon is known as the 'edge effect'.Increased edge area leads to greater exposure to external environmental factors,which reduces the stable 'core area' required by many species for survival.Therefore,both the Assertion and the Reason are correct,and the Reason provides a valid explanation for why habitat destruction leads to biodiversity loss.

$A$: Habitat destruction is the main reason for the loss of biodiversity.
$R$: This actually causes an increase in edge area and a reduction in core area.
