Question : Describe mutualism in detail. |
|
Answer» Solution :• Interaction conferring benefits on both the interacting species. • Lichens-mutualistic relationship between fungus and photosynthesising algae or cyanobacteria. • MYCORRHIZAE- mutualistic relationship between fungus and roots of higher plants. Fungi absorbs essential nutrients from soil and in return plant provides energy yielding carbohydrates to fungi. • Most spectacular and evolutionary fascinating example is plant-animal interaction. • Plant needs animals for POLLINATION, dispersal of SEEDS. • Animals are rewarded for their services in the form of pollens, nectars, juices, fruits and seeds. • In many species of fig trees, there is a tight one-to-one relationship with pollinator species of wasp. • Fig species is pollinated by its partner wasp and no other species. • Female wasp uses fruit not only as an OVIPOSITION (egg-laying) site but uses the developing seeds within fruit for nourshing its larvae. • The wasp pollinates the fig inflorescence while searching for suitable egg-laying SITES.
