The correct answer is: d) All of the above
Wetlands are areas of land that are saturated with water, either permanently or seasonally. They play an important role in the environment, providing a variety of benefits, including:
- Flood control: Wetlands can absorb and store floodwaters, helping to reduce the risk of flooding downstream.
- Water purification: Wetlands filter and clean water, removing pollutants and sediments.
- Fisheries and biodiversity: Wetlands provide habitat for a variety of fish and other aquatic life, as well as for birds and other wildlife.
- Recreation: Wetlands are popular for fishing, boating, and other recreational activities.
In Manipur, wetlands play an important role in all of these areas. For example, the Loktak Lake is a large wetland that provides flood control, water purification, and habitat for a variety of fish and other aquatic life. The lake is also a popular tourist destination.
Wetlands are a valuable resource that should be protected. However, they are often threatened by development and pollution. It is important to raise awareness of the importance of wetlands and to take steps to protect them.
