Vedclass · Answer

(A) During industrialization,the tree trunks became dark due to soot and smoke deposits.Dark-winged (melanised) moths were able to camouflage themselves against the dark background,making them less visible to predators like birds.In contrast,light-winged moths became conspicuous against the dark background and were easily preyed upon by birds.Therefore,the dark-winged moths had a higher survival rate and became more abundant.Both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the Assertion.

$A$: During industrialization,dark-winged or melanised moths were more abundant.
$R$: They were able to camouflage themselves,hide in the background,and survived.
