Question
Why are a fig tree and its partner wasp considered a good example of mutualism?

Answer

  1. It is a case of mutualism because both the fig tree and the Wasp are benefitted by this interaction.
  2. The female wasp uses the ovary of the flower as a site for oviposition and the developing seeds within the fruit for nourishing the larvae.
  3. The fig inflorescence is pollinated when the wasp is searching for a suitable place for egg-laying.
