- A A single, large, and largely continuous population occupying one habitat with no spatial subdivision into separate patches anywhere
- B A network of semi-isolated local populations connected by limited dispersal (colonization and extinction dynamics)
- C Populations that are restricted mainly to oceanic islands, rarely including any mainland or terrestrial populations
- D Populations of species that live mainly in aquatic habitats, excluding most terrestrial and amphibious species
Correct answer: B. A network of semi-isolated local populations connected by limited dispersal (colonization and extinction dynamics)
Explanation: Metapopulation (Levins): multiple subpopulations in patchy habitat connected by dispersal. Local populations go extinct; empty patches recolonized. Overall persistence depends on balance of colonization and extinction.
Concept context
Levels of biodiversity, species richness patterns, threats (HIPPO), and conservation strategies. Always in NEET.
