Solution
Commensalism is the interaction between two species in which one species derives benefit and the other one is neither harmed nor benefited. This is the interaction in which one species benefits and the other is neither harmed nor benefited.
An orchid growing as an epiphyte on a branch of a mango tree will benefit, while the mango tree derives no benefit.
The cattle egret and grazing cattle in close association are a classic example of commensalism. Cattle egrets always forage close to cattle; as cattle move, they flush out insects that might be difficult for the egrets to find and catch.
