Vedclass · Answer

(A) Population ecology provides the framework for understanding how ecological factors influence genetic variation and evolutionary processes within a group of individuals.Natural selection acts on the phenotypic variations present within a population,leading to changes in allele frequencies over generations,which is the fundamental mechanism of evolution.Since evolution occurs through changes in the genetic makeup of populations over time,population ecology is indeed a vital link between ecology and evolutionary biology.Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the Assertion.
