UPSC Prelims 2021 Question:

What is blue carbon?

Explanation:

The blue carbon ecosystems – mangroves, tidal and salt marshes, and seagrasses – are highly productive coastal ecosystems that are particularly important for their capacity to store carbon within the plants and in the sediments below.
  
  
• Green carbon is the carbon captured into terrestrial plant biomass in photosynthesis and stored in the plants and soil of natural ecosystems and is a vital part of the global carbon cycle.
  
  

Therefore, option (1) is the correct answer.
