What term refers to an interbreeding group of organisms?

• A. Species
• B. Community
• C. Ecosystem
• D. Population

Answer: (D)

An interbreeding group of organisms is a population. It refers to individuals of the same species that live in the same area and mate with one another, sharing a local gene pool. This concept matters because population-level processes—such as gene flow, genetic drift, and selection—shape allele frequencies over time within a specific locale. The other terms describe broader or different ideas: a species is the taxonomic category that groups potentially interbreeding populations and is often defined by reproductive isolation; a community includes all the living species in an area; an ecosystem adds the physical environment and energy flows to those living components. So the term that specifically captures the local interbreeding group is population.
