The fig tree and its specific pollinator, the fig wasp, exemplify a unique mutualistic relationship that showcases coevolution. In this relationship, the fig provides a specialized habitat and nourishment for the wasp, while the wasp facilitates pollination by transferring pollen from one fig to another as it lays its eggs inside the syconium. This interdependence highlights the complexity of ecological interactions and evolutionary adaptations, which are critical concepts often explored in the UPSC curriculum concerning biodiversity and ecosystem dynamics.
