A trait that increases an organism’s survival chances is called

• A. Adaptation
• B. Fossil
• C. Variation
• D. Evolution

Answer: (A)

An adaptation is a trait that helps an organism survive or reproduce in its environment. This makes it the best answer because it directly describes a characteristic that gives a survival or reproductive advantage, so it’s more likely to be passed on and become more common over generations through natural selection. For example, camouflage helps avoid predators, or a beak shape that matches available food helps an organism obtain nourishment more efficiently. Over time, these advantageous traits increase in frequency in the population. The other terms refer to different ideas: a fossil is a preserved remains from the past; variation means differences among individuals; evolution is the process by which populations change over time, which can include adaptations but is not a trait itself.
