Tides affect coastal ecosystems in several ways. The rising and falling of tides can impact the distribution of nutrients and sediments along the coast, influencing the habitats of various plants and animals. Tidal currents can also affect the movement and distribution of marine species, as well as the erosion and deposition of coastal landforms. Additionally, tidal fluctuations can regulate the salinity levels in estuaries, which are critical habitats for many species. Overall, tides play a significant role in shaping the dynamics and biodiversity of coastal ecosystems.
