Solution
Mutualism is a kind of population interaction in which both the participating species derive a benefit from each other’s presence. Examples of mutualism are given below:
- Associations between fungi and plants, called mycorrhizae: The plant benefits from essential soil nutrients that the fungus absorbs and transfers to the plant through its roots. The fungus, in turn, derives the benefit of receiving energy-yielding carbohydrates from the plant.
- Pollination: Plant flowers provide sweet, mucilaginous nectar to birds or insects in return for help spreading their pollen grains onto other flowers. The plant-pollinator pair often undergoes co-evolution to safeguard against other non-useful organisms using the nectar.
