Final answer:
The true statement about fig-fig wasp association is that it shows clear signs of coevolution, which is a mutualistic relationship where both the fig tree and the wasp benefit.Hence, option 1 is the correct answer.
Step-by-step explanation:
The statement about the fig-fig wasp association that is true is that 'These interactions show clear signs of coevolution'. In this mutualistic relationship, both the fig tree and the fig wasp benefit. The fig provides the wasp with a place to reproduce, and in return, the fig wasp pollinates the figs, ensuring the continuation of their species. This coevolution has resulted in specialized adaptations where each has become dependent on the other for survival.
Examples in nature of such relationships include the induction of flowering plants to produce attractive senses and food supplies to gain the favor of pollinating insects like bees. Similarly, certain insects have evolved features to take advantage of these offerings by plants. In the case of the fig wasp, it has developed the means to pollinate the fig while the fig has developed a structure that accommodates the lifecycle of the wasp.
