Wetlands are areas of land that are covered in water for all or part of the year. They include marshes, swamps, bogs, and fens.

The main types of wetlands are marshes, swamps, bogs, and fens. Marshes are wetlands that are dominated by grasses and other herbaceous plants. Swamps are wetlands that are dominated by trees and shrubs. Bogs are wetlands that are dominated by mosses and other peat-forming plants. Fens are wetlands that are dominated by sedges and other graminoids.

Wetlands are found all over the world. They can be found in tropical, temperate, and polar regions.

Wetlands provide habitat for a variety of plants and animals, help to control flooding, and help to filter pollutants from water.

Wetlands help to filter pollutants from water by absorbing pollutants into their plants and soils, breaking down pollutants into harmless substances, and trapping pollutants in their sediments.

Wetlands provide a source of food and water, help to control flooding, and help to filter pollutants from water.

Wetlands are threatened by pollution, climate change, and development.

Wetlands can be protected by reducing pollution, mitigating climate change, and protecting wetlands from development.

Wetlands are important because they provide habitat for a variety of plants and animals, help to control flooding, and help to filter pollutants from water.

Microorganisms in wetlands play a vital role in the purification of water. They decompose organic matter and release nutrients, remove pollutants from the water, and help to create new habitats for plants and animals.

Wetlands help to reduce flooding by storing excess water during heavy rains, slowing down the flow of water, and helping to create new channels for water to flow.

Cattails, reeds, and sedges are all commonly found in wetlands.

Frogs, toads, and salamanders are all commonly found in wetlands.

Pollution, climate change, and development are all threats to the health of wetlands.
