Changing Coral Reef Quick Check
Q1. What is a coral reef?
A1. A coral reef is a marine ecosystem formed by colonies of coral polyps that secrete calcium carbonate to create a hard exoskeleton.
Q2. How are coral reefs important to marine ecosystems?
A2. Coral reefs support a wide variety of marine life, including fish, invertebrates, and other organisms. They provide habitat, food, and protection for many species.
Q3. What are some threats to coral reefs?
A3. Some threats to coral reefs include overfishing, pollution, climate change, and ocean acidification. These factors can lead to coral bleaching, disease outbreaks, and habitat destruction.
Q4. How can we protect coral reefs?
A4. Conservation efforts such as marine protected areas, sustainable fishing practices, reducing pollution, and addressing climate change can help protect coral reefs. Individuals can also make a difference by practicing responsible tourism and reducing their carbon footprint.
Q5. What is coral bleaching and why is it a concern for coral reefs?
A5. Coral bleaching occurs when corals expel the algae living in their tissues, causing them to turn white. This is often a response to environmental stress, such as high water temperatures or pollution. Bleaching weakens corals and can lead to their death if conditions do not improve, posing a serious threat to coral reef ecosystems.
