Vedclass · Answer

(D) Plants have evolved various morphological and chemical defenses to protect themselves from herbivores.$I.$ Production of secondary metabolites like caffeine,tannin,and quinine acts as a chemical defense to deter herbivores.$III.$ Morphological structures such as hairs,thorns,and spines act as physical barriers against grazing animals.$IV.$ Some plants produce hormone-like chemicals that interfere with the metamorphosis of insects,thereby preventing them from reaching the adult stage.$II.$ The production of non-woody tissues is not a defense mechanism against herbivory.Therefore,the correct pair is $I, III$ and $IV$.

Column $I$	Column $II$
$A$. Calotropis	$i$. Invertebrates
$B$. Pisaster	$ii$. Distasteful
$C$. Monarch butterfly	$iii$. Cryptically coloured
$D$. Frogs	$iv$. Cardio glycosides

Column-$I$	Column-$II$
$(a)$ Herbivores-Plants	$(i)$ Commensalism
$(b)$ Mycorrhiza-Plants	$(ii)$ Mutualism
$(c)$ Sheep-Cattle	$(iii)$ Predation
$(d)$ Orchid-Tree	$(iv)$ Competition
