Awetland, or marshes, is a distinct ecosystem that is inundated by water, either permanently or seasonally, where oxygen-free processes prevail. many habitats that are rich in plant life are important stores of carbon. how do marshes lock away carbon?

Marshes are wetlands

Explanation: When plants within the Marshes die,rather than decompose through Microbial activities and release their Carbon into the atmospheres,the carbon remain buried within the muddy soil and due to the impact of the waves Microbial activities are slowed and in most cases prevented,As the ocean waves finds its path through the mashes more matters are deposited on the buried plants locking the carbon and preventing the release of carbon.

This is one of the main importance of the wetlands like mashes on climate change.
