Final answer:
Fitness in adaptation refers to the ability of an organism to survive and reproduce. Camouflage and mimicry can enhance an organism's fitness by increasing its chances of survival and reproduction.
Step-by-step explanation:
Fitness, as it relates to adaptation, refers to the ability of an organism to survive and reproduce in its environment. Adaptations such as camouflage and mimicry can increase an organism's fitness by enhancing its chances of survival and reproduction. Camouflage is an adaptation where an organism has colours, patterns, or shapes that help it blend into its surroundings, making it difficult for predators or prey to detect it. This increases its chances of survival by reducing the risk of being eaten. Mimicry is an adaptation where an organism resembles another organism or object, providing protection from predators or increasing its chance of capturing prey. For example, a non-poisonous dart frog may evolve to look like a poisonous dart frog, which deters predators from attacking it.
