Vedclass · Answer

(D) In a tree ecosystem,a single tree (producer) has a much larger biomass than the herbivores (birds,insects) that feed on it. Therefore,the pyramid of biomass for a tree ecosystem is inverted,not upright. Since the assertion states that the pyramid is always upright for a tree ecosystem,the assertion is incorrect. The reason provided is also incorrect because the biomass of a single tree is indeed greater than that of the herbivores,but this leads to an inverted pyramid,not an upright one.

$A$: Pyramid of biomass is always upright for tree ecosystem.
$R$: Total biomass of a tree in a specific area is more than that of herbivores.
