There are three water ecosystems: saltwater ecosystem, freshwater ecosystem and brackish water ecosystem.
freshwater ecosystems are fresher
The three categories of freshwater ecosystems are lentic ecosystems (still water, like lakes and ponds), lotic ecosystems (flowing water, like rivers and streams), and wetlands (areas of land saturated with water, like marshes and swamps).
Approximately 30.1% of Earth's fresh water is stored in aquifers. These underground reservoirs are crucial for supplying water to wells and springs, as well as supporting ecosystems and human water needs.
Three types of freshwater ecosystems found in Florida are wetlands, such as the Everglades, rivers like the St. Johns River, and lakes including Lake Okeechobee. These ecosystems support diverse wildlife and plant species and play a crucial role in water filtration and flood control. Florida's unique geography and climate contribute to the rich biodiversity within these freshwater habitats.
