What are the relationships between the biotic and abiotic features of the great barrier reef?

The Great Barrier Reef's biotic features, such as coral, fish, and marine plants, interact closely with its abiotic components, including water temperature, salinity, and sunlight. Coral reefs thrive in warm, shallow waters that allow sunlight to penetrate, enabling photosynthetic algae (zooxanthellae) to live within coral tissues and provide essential nutrients. Additionally, the nutrient levels and water quality directly influence the diversity and health of marine life. Changes in abiotic factors, such as increased temperature or pollution, can disrupt these relationships, leading to coral bleaching and loss of biodiversity.
