Study Notes
Coral Reefs: Definition
- Coral reefs are bustling underwater communities of diverse plants and animals.
- The "buildings" of reefs are corals, which are living animals.
- Reefs are found in warm, clear, shallow tropical waters.
- Different coral species and organisms thrive in specific reef areas based on environmental conditions.
- Reef environment is not naturally nutrient-rich; nutrients are provided by zooxanthellae through photosynthesis.
- Corals and zooxanthellae have a symbiotic relationship, exchanging nutrients (e.g., carbon dioxide, ammonia).
Coral Reefs: Types
- Barrier reefs: Separated from land by a lagoon, like the Great Barrier Reef.
- Atolls: Circular reefs with central lagoons, often formed on submerged volcanoes.
- Fringing reefs: Found close to volcanic islands or continents.
Coral Reefs: Importance
- High productivity supports a wide variety of marine life (fish, plants, etc.).
- Provide shelter and protection from predators.
- Aid in coastal protection against flooding.
- Attract tourists and divers, contributing to local economies.
- Examples of common reef inhabitants include sea anemones, sea stars, sea sponges, clams, octopuses, eels, sea urchins, barracudas, and clownfish.
Coral Reefs: Conservation
- Coral reefs naturally form and break down; human activities also impact them.
- Overfishing can harm unique species.
- Rising ocean temperatures cause coral bleaching due to zooxanthellae loss.
- Pollution (changes in salinity, nutrients, oxygen) harms reef organisms.
- Crucial to protect reefs for the survival of diverse marine life and the associated economic benefits.
