Answer :

Final answer:

Wetlands are essential for flood control, water purification, and biodiversity.


Explanation:

Wetlands play a crucial role in flood control by storing excess water from floods and runoff, slowing down runoff to prevent erosion, and reducing flood heights. They also purify water by filtering sediments and toxins before they enter rivers, lakes, and oceans. Additionally, wetlands provide a unique habitat for various plant and animal species, contributing to high biodiversity.
