wetland
A wetland is a type of ecosystem where water covers the land or is present near the surface for at least part of the year. This creates a unique environment that supports diverse plants and animals adapted to wet conditions. Wetlands include areas like swamps, marshes, and bogs. They play a vital role in filtering water, controlling floods, and providing habitat for wildlife. Because they are rich in nutrients and biological activity, wetlands are important for maintaining ecological balance and supporting biodiversity.
