In the study of Oregon intertidal communities, little brown barnacles (Chthamalus dalii) are first to colonize disturbed areas. Over time, the acorn barnacle (Balanus glandula) dominates the community. Which mechanism of succession explains the relationship between the two species of barnacles?

Inhibition is the mechanism that explains the relationship between the two species of barnacles. Initially, the little brown barnacles colonize the area, but as the acorn barnacle arrives, it outcompetes the little brown barnacles for space and resources, eventually dominating the community. This process is characterized by one species inhibiting the growth or survival of another through competition or other means, which aligns with the concept of inhibition in ecological succession.
