Final answer:
An individual organism with higher fitness is more likely to reproduce.
Step-by-step explanation:
An individual organism that exhibits a higher fitness level is more likely to reproduce. Fitness refers to an organism's ability to survive and reproduce in its environment. Organisms with higher fitness are better adapted to their environment, have more chances to reproduce, and pass on their advantageous traits to their offspring. This increases the probability of their genes being passed on to future generations.
