Question

an organism that is best fit for its environment has _______ that help it survive.

Explanation:

The question asks for traits that help an organism survive in its environment. Adaptations are specific features or behaviors that enhance an organism's survival and reproduction in its habitat. Evolution is the process of change over time, overpopulation refers to excess individuals, and selection is the mechanism driving adaptation—none directly describe the survival traits themselves.
