Which factor contributes to a species' ability to thrive over time?

• A. High population density
• B. Limited genetic variation
• C. A wide variety of traits within the species
• D. Decreased reproductive rates

Answer: (C)

A wide variety of traits within a species enhances its ability to thrive over time due to the principle of genetic diversity. When a species exhibits a diverse range of traits, it increases the likelihood that some individuals will possess traits advantageous for survival in changing environmental conditions. This variation can include traits related to physical characteristics, behaviors, and reproductive strategies, which can contribute to better adaptation, resilience, and overall fitness in various habitats. For example, if environmental conditions change—such as shifts in climate, availability of food, or new predators—having a range of traits allows certain individuals to adapt more effectively than others. This trait diversity can lead to a robust population that can withstand challenges and continue to reproduce successfully. Other factors, like high population density and limited genetic variation, can negatively impact a species' ability to thrive. Additionally, decreased reproductive rates could hinder population growth, making it harder for a species to recover from environmental pressures. Thus, the presence of a wide variety of traits is crucial for ensuring long-term survival and adaptability in the face of dynamic ecosystems.
