Dear Student,
1.Mangrove forests are the also green forest ecosystem on Earth. They can be found in the salt water coastal regions of 118 tropical and subtropical countries, which is more than 1,37,000 square kilometres. They have the potential to enhance the quality of water by purifying contaminants and trapping sediments from the soil.
2.Mangrove forests are characterised by a humid climate, saline environment, and soil. A variety of offshore and coastal organisms rely solely on mangrove forests for their habitat. Mangroves can reduce coastal erosion. It also functions as a fertilising site for a variety of aquatic fauna resulting in biodiversity.
3.Relevant features of mangrove forests include adaptation to low levels of oxygen, absorption of nutrients from the environment, reducing salt consumption, increasing the survival of the offspring and limiting the loss of water.
4.Mangrove forests play an important part in preserving the structure of marine ecosystems.
I hope the answer will serve your purpose.
