Answer: Coevolution
Step-by-step explanation:
Coevolution can be define as the successive changes that occur simultaneously in two or more than two ecologically interdependent species that affects their interaction.
The given situation is an example of coevolution. This is because of the fact that the moth is adapted to feed over different food sources (plants) and on it's feeding behavior the plants are pollinated. This way both the moth and plant species are evolving. Thus it is an example of coevolution.
