Describe commensalism.

(N/A) Commensalism is a type of population interaction between two species where one species benefits and the other is neither harmed nor benefited.
In this interaction,the species that benefits is called the commensal,while the other species remains unaffected.
Examples include:
$1$. An orchid growing as an epiphyte on a mango branch,where the orchid gets support and sunlight,while the mango tree is unaffected.
$2$. Barnacles growing on the back of a whale,which gain a place to live and access to moving water for food,while the whale is neither harmed nor helped.
