A pond ecosystem is a small, freshwater habitat that supports a variety of living organisms. It typically includes water, plants, and animals, all interacting with each other. Common plants found in ponds are water lilies and cattails, which provide shelter and food for various species. Inhabitants of a pond ecosystem include fish, frogs, insects, and birds. These organisms play essential roles, such as predators, prey, and decomposers, helping to maintain the balance of the ecosystem. The health of a pond is influenced by factors like water quality, temperature, and the presence of nutrients.
