Raccoons, ducks, geese, and swans visit ponds. There are many smaller animals as well. Frogs, toads, and many insects begin their lives in ponds and live nearby after they are grown. Turtles, snakes, rats, salamanders, worms, and spiders can also be found.
Answer:
A pond is an area filled with water, either natural or artificial, that is smaller than a lake.[1] Ponds may arise naturally in floodplains as part of a river system or can simplify be an isolated depression (such as a kettle, vernal pool, or prairie pothole) that filled with runoff, groundwater, or precipitation.[2] As such, ponds may be freshwater, saltwater, or brackish in nature.Many ponds contain shallow water ecosystems with varying abundances of aquatic plants and animals. Certain characteristic such as depth, seasonal water level, nutrients fluxes, solar radiation, degree of inlets and outlets, local organisms, and salinity may affect the types of ecosystems present within a pond.[3]
Ponds are frequently man-made or expanded beyond their original depths and bounds by anthropogenic causes. Among their many uses, ponds provide water for agriculture, livestock and communities, aid in habitat restoration, serve as breeding grounds for local and migrating species, are components of landscape architecture, flood control, general urbanization, mitigate particular pollutions and greenhouse gasses, and support wide varieties of organismal ecosystems.
