What organisum do swan live in?

Swans primarily live in freshwater habitats such as lakes, rivers, and ponds, where they can find ample food sources like aquatic plants, insects, and small fish. They are also known to inhabit brackish waters in coastal areas. Swans often form monogamous pairs and can be seen gliding gracefully on the water or foraging on land near their habitats. In addition to their natural environments, they may also be found in parks and reserves where they are protected and cared for by humans.
