Answer:
coevolution
Step-by-step explanation:
- When two species evolve in a tandem manner because one species exerts a selection pressure on another is termed as coevolution.
- In coevolution the evolution of one species is reciprocated by the evolution of other species.
- Coevolution can occur between species that mutually depend on each other, are forming a host-parasite relation, are competing with each other or are in a prey-predator relationship.
- In the given case, it is mentioned that the plant is evolving to have a higher level of poison and this is in-turn causing the insect to evolve and produce an enzyme that can break down the poison, so the plant here is exerting a selection pressure on the insect and hence, is causing the insect to evolve as the plant evolves.
- Thus, the given scenario is an example of co-evolution.
