Final answer:
The hierarchy from the most inclusive to the least complex level is 'local population < metapopulation < species < subspecies', reflecting the organization from specific localized groups to broader classifications.
Step-by-step explanation:
The correct hierarchy of the population concept from the most inclusive to the least complex level is local population < metapopulation < species < subspecies. A local population is a group of individuals of a species that live in a specific area and have limited gene flow with other such groups. A metapopulation consists of a group of spatially separated populations of the same species which may exchange individuals through migration or emigration. Species, then, is a group of similar organisms capable of interbreeding and producing fertile offspring, and subspecies are a further division within a species that have noticeable morphological or genetic differences.
