Assertion and Reason both are correct but Reason is not the correct explanation of Assertion.

Vedclass · Answer

(B) The $Assertion$ is correct because, according to Gause's Competitive Exclusion Principle, two species competing for the same limiting resources cannot coexist indefinitely in the same ecological niche; thus, a niche is typically occupied by a single species.The $Reason$ is also correct because many different species can share the same physical habitat (the place where an organism lives) while occupying different ecological niches to avoid direct competition.However, the $Reason$ does not explain why a niche is occupied by a single species; rather, it highlights the distinction between habitat and niche. Therefore, $B$ is the correct answer.

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

$A$: An ecological niche is usually occupied by a single species.
$R$: More than one species can live in the same habitat.
