Question
Mutualism
✓
Answer
Mutualism is an obligatory and interdependent interaction. It is an association of two species in which both of them are benefited.
The classic example of mutualism is lichens. Lichen is an intimate, mutualistic relationship between a fungus and photosynthetic algae or cyanobacteria.
Most of the plant and animal interactions are of mutualistic type.
For pollination and seed dispersal, plants depend on the animals.
Animals in turn feed on pollen and nectar during pollination. During seed dispersal juicy and nutritious fruits are used by the animals.
In animal-animal interactions also mutualism is seen in many instances.
