The correct answer is option 3. "Tidal forest” is otherwise called a mangrove forest. These forests are found in coastal areas and are characterized by the presence of mangrove trees, which are specially adapted to survive in saline and tidal conditions. Mangroves have unique prop roots that help them anchor in muddy soil and withstand strong tides and waves. They also have specialized adaptations to deal with the high salt content in the water. These forests are important ecological habitats as they provide nesting sites for many bird species, serve as nurseries for various marine organisms, and act as a buffer against coastal erosion and storm surges. The term "tidal forest" is often used interchangeably with "mangrove forest" due to the close association of mangroves with tidal environments.
