A. Camargue (France)
B. Okavango (Botswana)
C. Everglades (USA)
D. Pantanal (South America)

Answer 1

Hint: The word wetland refers to the area which is filled with water. The characteristic vegetation of aquatic plants differs from wetlands from other landforms or water bodies. Various functions are performed by wetlands which are important for the balance of nature.

Complete answer: A ecosystem that is flooded by the water where oxygen-free processes prevail is called wetlands. Functions such as water purification, processing of carbon and other nutrients, water storage, support of plants and animals, and stabilization of shorelines are regulated by wetlands. The most biological diversity of all ecosystems is wetlands which serve as a home to a wide range of animal and plant life. On every continent, wetland occurs naturally. Wetlands consist of brackish, freshwater, or saltwater. Marsh, swamp, fen, and bog are the main types of wetlands. A natural region which encompasses the world’s largest flooded grasslands and the world’s largest tropical wetland areas is Pantanal. It covers an estimated area between 140,000 and 195,000 square kilometers. During the rainy season, 80 percent of the Pantanal floodplains are submerged which nurtures the biological diverse collection of aquatic plants and helps large species of animals. Camargue is located in the south of Arles, France. It is a natural region. Okavango, a swampy inland delta is located in Botswana. A natural region of tropical wetlands situated in the southern part of the USA comprises the large drainage basin called Everglades. The ecosystem formed in Everglades is not found anywhere else in the world. Therefore, it is clear that Pantanal is the world’s largest wetland ecosystem.
So, option C is the correct answer.

Note: The Amazon River basin, Pantanal, the Sundarbans of India, and West Siberian Plain are included in the largest wetlands. Another type of wetland that is found in the forest of the Gulf Coast states in the USA is the bay gall. Wetlands are one of the assets of nature.
