Final answer:
Tropical figs are predominantly pollinated by fig wasps, which is a form of mutualistic symbiotic relationship, showcasing high specialization in tropical ecosystems.
Step-by-step explanation:
The kind of organism that pollinates tropical figs is the fig wasp. This is an example of a mutualistic symbiotic relationship where both organisms benefit. In the case of tropical fig trees and fig wasps, the fig wasps pollinate the figs, ensuring the continuation of the fig tree's life cycle, while in return they gain a place to lay their eggs, which in the case of figs, is actually inside the fruit. This intricate pollination process, which often involves a single species of fig wasp being adapted to pollinate a specific type of fig, demonstrates the high degree of specialization and interdependence in tropical ecosystems. Over time, the development of such specific mutualistic relationships has played a crucial role in the diversity and survival of many plant and insect species.
