Vedclass · Answer

(C) Tropical rain forests receive high amounts of rainfall,which leads to intense leaching of nutrients from the soil.Leaching is the process where water-soluble nutrients are washed away from the soil profile.Due to this high rate of leaching,the soil in these regions typically has a low base content and is often acidic.Therefore,the Assertion is correct because the soil has low base content,but the Reason is incorrect because these soils actually show high rates of percolation and leaching,not less.

Column-$I$	Column-$II$
$(i)$ Primary succession	$(i)$ Development of ecosystem
$(ii)$ Ecological succession	$(ii)$ Lichens
$(iii)$ Pioneer species on rocks	$(iii)$ Near to the equilibrium with the environment
$(iv)$ Climax community	$(iv)$ New species on bare environment

$1$. Standing state	$p$. Mass of living material at a given time
$2$. Pioneer species	$q$. Amount of nutrients in the soil at a given time
$3$. Detritivores	$r$. Species that invade a bare area
$4$. Standing crop	$s$. Breakdown detritus into smaller particles

$A$: The soil of tropical rain forests has a low base content.
$R$: Such soil shows less percolation and leaching.
