Final answer:

Salt in coastal areas acts as a limiting factor, affecting the types of species that can survive. Estuaries are crucial areas influenced by salinity that serve as nurseries for various marine species.


Explanation:

Salt in coastal areas functions as a limiting factor, determining which species can exist there. The short-term and rapid variation in salinity poses a physiological challenge for plants and animals, leading to adaptations like halophytes and behavioral changes in aquatic species like mussels and clams. Estuaries, where freshwater meets the ocean, serve as nursery grounds and are heavily influenced by salinity levels.
