"Biorock technology" is talked about in the context of the restoration of damaged coral reefs. Biorock technology is a method that involves the use of low voltage electrical currents to promote the growth of calcium carbonate on a metal structure, which is then used as a substrate for coral to grow. This process can help accelerate coral growth, provide a stable habitat for marine organisms, and enhance the resilience of coral reefs to environmental stressors. Therefore, option 1 is the correct answer. The other options do not relate to biorock technology.

 

Preparing for Future Exams: Learning from the Analysis of Past Questions

Topic: Environmental Science, Marine Biology

Concepts to be studied:

  • Coral reefs and their importance
  • Reef degradation and restoration methods
  • Biorock technology and its working
  • Sustainable technology for marine conservation

Sources:

  • NCERT Biology textbooks for Class 11 and 12
  • Reference book: "Coral Reefs" by Charles Sheppard
  • Online resources such as the Global Coral Reef Alliance website and the Reef Resilience Network website

NCERT Biology textbook chapters:

  • Class 11: Chapter 15 - Biodiversity and Conservation
  • Class 12: Chapter 16 - Environmental Issues

Reference book chapters:

  • "Coral Reefs" by Charles Sheppard - Chapters 7 and 8 on Coral Reef Degradation and Restoration

Related concepts:

  • Marine ecosystems
  • Sustainable technology
  • Conservation biology
  • Climate change and its impact on marine ecosystems

In addition, it would be helpful to study the applications and benefits of biorock technology in coral reef restoration and the various projects and initiatives that have used this technology.
