What the advantage that bacteria and fungi gain from synthesis of antibiotic?

Bacteria and fungi produce antibiotics as a means of survival and competition. By synthesizing these compounds, they can inhibit the growth of neighboring microorganisms, thereby reducing competition for resources such as nutrients and space. This ability allows them to establish dominance in their ecological niches and increases their chances of survival and reproduction. Additionally, antibiotic production can help protect them from being preyed upon by other organisms.
