Tides play a crucial role in shaping coastal ecosystems by influencing various factors such as water levels, nutrient availability, and sediment movement. The regular ebb and flow of tides provide essential oxygen and nutrients to intertidal habitats, supporting diverse marine life. Tidal changes also help distribute seeds, larvae, and nutrients along the coast, contributing to biodiversity and ecosystem health. However, extreme tides or fluctuations can disrupt coastal ecosystems, leading to erosion, habitat loss, and changes in species composition. Overall, tides are a fundamental driver of coastal ecosystem.
