Consider the following statements about wetlands. Which of the following is incorrect?
Wetlands are rich in nutrients and they transfer these nutrients to water
A wetland is a place where the land is covered by water, either salt, fresh or somewhere in between.
Wetland soil is an important carbon sink; 14.5% of the world’s soil carbon is found in wetlands, while only 6% of the world’s land is composed of wetlands
Wetlands remove excessive nutrients from water and allow the particulate matter to settle down which can be then used by plants. It has been proved that 90% of phosphorus can be removed from passing water through wetland.
The most significant social and economic benefit that wetlands provide is flood control. Peatlands and wet grasslands alongside river basins can act like sponges, absorbing rainfall and controlling its flow into streams and rivers.
Although paddy fields were originally wetlands and artificially constructed devices for rice production, they have worked as a nursery of biodiversity and cultural diversity.
