Tides play a critical role in shaping coastal ecosystems. The rise and fall of tides bring in nutrients, sediments, and marine organisms, which contribute to the biodiversity and productivity of coastal habitats. For example, the ebb and flow of tides help oxygenate tidal flats and marshes, supporting the growth of plants and animals. Tidal currents also influence the distribution of species and help in the transport of larvae and nutrients along the coast. Additionally, tides can cause erosion and deposition of sediments, shaping the physical structure of coastal ecosystems. Overall, tides have a significant impact on the health and functioning of coastal ecosystems.
