Q. Which of the following is/are comes under blue carbon?
2.Tidal Marshes
3.Sea grasses
Choose the correct answer from below given codes:

[A] 1 only

[B] 1 and 2 only

[C] 2 and 3 only

[D] 1, 2 and 3

Answer: D

Explanation: Blue Carbon refers to coastal, aquatic and marine carbon sinks held by the indicative vegetation, marine organism and sediments.

  • In particular, coastal ecosystems such as tidal marshes, mangroves, and sea grasses remove carbon from the atmosphere and ocean, storing it in plants and depositing it in the sediment below them by natural processes.
  • These coastal ecosystems are very efficient at sequestering and storing carbon – each square mile of these systems can remove carbon from the atmosphere and oceans at rates higher than each square mile of mature tropical forests.
