Which example best illustrates adaptations that support survival under changing environmental conditions?

• A. Drought tolerance
• B. Drought tolerance, camouflage, and efficient water use
• C. Large body size alone
• D. Inability to adjust to changing conditions

Answer: (B)

Traits that help an organism survive when the environment changes. When conditions shift, having multiple adaptive strategies worked into one set of traits gives a better chance of surviving. Drought tolerance helps organisms endure low water availability, which is key when climates become drier or droughts last longer. Camouflage reduces the risk from predators (or helps catch prey) as habitats change and look different, making survival more likely across different environments. Efficient water use minimizes water loss and makes the most of limited resources, a crucial boost during changing conditions.

Large body size alone doesn’t guarantee resilience to changing environments; it may help in some situations, but it doesn’t provide the suite of coping strategies needed for variable conditions. The inability to adjust to changing conditions offers no advantage at all and would reduce survival as the environment shifts.
