Answer

Brief Explanations:

  1. Coral reefs contribute to marine ecosystem health by providing habitats for numerous species, protecting coastlines from erosion, and facilitating nutrient - cycling.
  2. Coral reef formation starts with coral polyps secreting calcium carbonate exoskeletons. Over time, these build - up to form reefs. Coral polyps are the fundamental building blocks.
  3. The symbiotic relationship between corals and zooxanthellae is significant as zooxanthellae perform photosynthesis, providing corals with energy and oxygen, while corals offer a protected environment and nutrients.
  4. The three main types are fringing reefs (close to shore), barrier reefs (parallel to shore with a lagoon in between), and atolls (ring - shaped reefs around a lagoon). They differ in location and structure.
  5. Ocean acidification reduces the availability of carbonate ions, which are essential for corals to build their calcium carbonate skeletons, thus weakening and endangering reef health.
  6. Economically, coral reefs support tourism (snorkeling, diving) and fishing industries. Tourism brings in revenue through visitor spending, and fishing provides livelihoods and food resources.
  7. Signs of coral bleaching include a change in color from vibrant to white. High water temperatures, pollution, and increased solar radiation typically lead to this.
  8. Pollution can smother corals, reduce water quality, and disrupt the symbiotic relationship between corals and zooxanthellae, harming reefs and their surrounding ecosystems.
  9. In the Maldives, conservation strategies may include marine protected areas, coral gardening (growing corals in nurseries and transplanting them), and education programs to raise awareness.
  10. Climate change affects coral reef biodiversity by causing coral bleaching and mortality, reducing species habitats. It also decreases reef resilience as rising sea temperatures and ocean acidification make it harder for reefs to recover.

Answer:

  1. Provide habitats, protect coastlines, and facilitate nutrient - cycling.
  2. Coral polyps secrete calcium carbonate exoskeletons; they are the building blocks.
  3. Zooxanthellae provide energy and oxygen, corals offer protection and nutrients.
  4. Fringing reefs (close to shore), barrier reefs (parallel with lagoon), atolls (ring - shaped around lagoon); location and structure.
  5. Reduces carbonate ions, weakens coral skeletons.
  6. Support tourism (visitor spending) and fishing (livelihoods and food).
  7. Color change to white; high water temperatures, pollution, increased solar radiation.
  8. Smothers corals, reduces water quality, disrupts symbiosis.
  9. Marine protected areas, coral gardening, education programs.
  10. Causes bleaching and mortality, reduces biodiversity and resilience.
