Wetlands are important for all of the following reasons except option D

Explanation:

Wetland is a ecosystem which contain water that is present either seasonally or permanently and this water body is rich in species diversity as the water body contain high amount of minerals.w

They are natural detoxifier as they have the capability to reduce the effect of harmful substance that may enter into the ponds, lakes or other water body thus it is also called as the natural kidney of ecosystem.

They reduce the chance of flood by temporarily storing the release of storm water which allows the formation of sediments in the bottom of the water body.
