What is the term for the variety of life in an area?

• A. Dominant allele
• B. Biodiversity
• C. Heredity
• D. Pioneer species

Answer: (B)

Biodiversity is the variety of life in a given area, encompassing genetic diversity within species, the number of different species, and the variety of ecosystems. This diversity shapes how ecosystems function and respond to changes, influencing resilience, productivity, and stability. Dominant allele is a genetic term about which version of a gene is expressed, not about life variety in an area. Heredity refers to the passing of traits from parents to offspring. Pioneer species describes the first organisms to colonize a disturbed area, related to ecological succession rather than overall life diversity. The term that best fits the description is biodiversity.
