2. What is the term for a group of organisms that can interbreed and produce fertile offspring?

• A. Genus
• B. Phylum
• C. Kingdom
• D. Species

Correct answer: D

Rationale: Rationale: A species is defined as a group of organisms that can interbreed and produce fertile offspring. This ability to interbreed and produce fertile offspring is a key characteristic that distinguishes one species from another. In contrast, a genus (option A) is a taxonomic rank that includes one or more species that are closely related, while a phylum (option B) and a kingdom (option C) are higher taxonomic ranks that encompass multiple species.
