Answer 1

Answer:

Commensalism. A commensal relationship occurs when one species benefits from the close, prolonged interaction, while the other neither benefits nor is harmed. Birds nesting in trees provide an example of a commensal relationship (Figure 1). The tree is not harmed by the presence of the nest among its branches.
