A freshwater ecosystem refers to a set of living and non-living components that exist in freshwater sources. Some synonyms for the term include freshwater biome, freshwater habitat, and freshwater environment. These synonyms encompass the various forms of water environments such as rivers, lakes, ponds, and wetlands. These ecosystems support a diverse range of organisms such as fish, reptiles, amphibians, mammals, and a host of invertebrates. The freshwater environment is essential to the survival of a wide range of species, as it provides an ideal habitat for spawning, feeding, and nesting. Preserving these ecosystems is critical for maintaining biodiversity and ensuring the continued existence of many species that depend on them.
