Detailed explanation-1: -Commensalism: In commensalism, one organism benefits while the other organism neither benefits nor suffers from the interaction. For example, a spider may build a web on a plant and benefit substantially, while the plant remains unaffected.

Detailed explanation-2: -Commensalism happens when one species lives with, on, or in another species, known as the host. The host species neither benefits nor is harmed from the relationship.

Detailed explanation-3: -The simplest example of commensalism is a bird making a nest in a tree. The tree provides shelter and protection to the bird without getting significantly harmed or affected by the bird. Another typical example is the cattle egrets (birds) that feed upon the insects stirred up by the feeding cattle.

Detailed explanation-4: -Bacteria, fungi, and mites form the commensal flora and fauna on the skin. The fungi Malassezia furfur and Candida albicans are found on the skin of some individuals. All humans can act as hosts to skin mites such as Demodex folliculorum and Demonex brevis.
