Tides affect coastal ecosystems in various ways. The ebb and flow of tides help to circulate nutrients, oxygen, and other essential elements within coastal habitats, which can support diverse marine life. Tides also shape coastal landscapes through erosion and sediment deposition, influencing the distribution of plants and animals. Additionally, tides play a role in regulating the breeding, feeding, and migration patterns of many species that rely on coastal ecosystems for survival. Overall, tides are a crucial component of coastal ecosystems, shaping their biodiversity and ecological processes.
