Plants typically grow along the shore. In a pond, temperatures are fairly uniform from top to bottom and tend to change with the air temperature. Within a pond ecosystem there are habitat zones where distinct groups of plants and animals are found. Other shallow ponds were created artificially in existing low-lying areas in order to attract wildlife and harbor mosquito predators. There are no naturally occurring ponds in this area.
Ponds are relatively short-lived ecosystems.
They gradually fill with organic debris and vegetation.
