Heading (Title of the Paragraph): Coral Reefs and Intertidal Zones
A. First major point (topic sentence): Coral reefs and intertidal zones serve as critical ecosystems that support a diverse range of marine life and play vital roles in coastal protection and nutrient cycling.
Supporting detail idea 1: Coral reefs are often referred to as the "rainforests of the sea" because they provide habitat for a multitude of species, including fish, invertebrates, and marine mammals, contributing to overall biodiversity.
Supporting detail idea 2: Intertidal zones host unique organisms adapted to the fluctuating conditions of tide and wave exposure, allowing for a distinct community of plants and animals, such as barnacles, seaweeds, and crabs.
Supporting detail idea 3: Both coral reefs and intertidal zones protect coastal areas from erosion and storm damage, highlighting their importance not just for marine ecosystems, but also for the livelihoods and safety of human communities that depend on these environments.
