The ecological significance of intertidal zones lies in their unique biodiversity and dynamic environments. These zones serve as critical habitats for a variety of species, including invertebrates, fish, and plant life, which adapt to the challenging conditions of changing tides. Intertidal zones also play a role in nutrient cycling and serve as feeding grounds for birds and other wildlife. Furthermore, they act as buffers against coastal erosion and are important in maintaining marine ecosystem health and resilience.
