Vedclass · Answer

(A) Ecological pyramids are based on the assumption of a simple food chain,whereas in nature,a complex food web exists.Because of this,pyramids fail to account for organisms that occupy more than one trophic level simultaneously (e.g.,omnivores).Therefore,they cannot represent all the vital functions or the complete energy flow of an ecosystem.Both the Assertion and the Reason are correct,and the Reason provides a valid explanation for the limitation mentioned in the Assertion.

$A$: Ecological pyramids cannot explain all the vital functions of any ecosystem.
$R$: Pyramids actually do not explain the role of organisms working at more than one trophic level.
