What does the intertidal zone represent in a marine biome?

The intertidal zone is the region of the shoreline that is exposed to the air at low tide and submerged under water at high tide. This dynamic environment occurs where land meets water, defining its unique ecological characteristics. Organisms in this zone have adapted to the changing conditions of being submerged and exposed, such as variations in salinity, temperature, and desiccation stress.

It is important to note that while the intertidal zone does include areas that are submerged at high tide, it is primarily characterized by the alternating exposure between land and water. The intertidal zone is essential for understanding marine biodiversity as it supports various species that are specially adapted to such fluctuating environments. This makes the intertidal zone a critical area for studying ecological interactions between marine and terrestrial environments.
