Question
Describe the mutual relationship between the fig tree and wasp and comment on the phenomenon that operates in their relationship.
✓

Answer

The relationship between fig tree and wasp shows mutualism. The wasp while searching for sites to lay its eggs, pollinates the fig's inflorescence. On the other hand, the fig not only provides shelter (fruit) for oviposition but also allows wasp's larva to feed on its seeds.
