Answer:
This is an illustration of coevolution.
Step-by-step explanation:
The procedure by which two or more species evolve in tandem by imparting selection pressures on each other is known as coevolution. The examples of coevolutionary systems comprise predators and prey, host and parasites, and symbiotic or mutualistic associations. Thus, the given association between the moth and orchid is an example of coevolution as both the species of moth and orchid are getting evolved in the company of each other, that is, by imparting selection pressures on each other.
