Tides significantly impact coastal ecosystems by influencing habitat availability, nutrient distribution, and species behavior. The rising and falling of tides can create a dynamic environment that shapes the coastal landscape. For example, intertidal zones are exposed during low tide, providing opportunities for organisms to feed and reproduce, while high tide may bring in nutrients and sediments to nourish coastal habitats. Additionally, the movement of water during tides can affect the distribution of plankton and other food sources, which in turn influences the entire food chain within coastal ecosystems.
