Aquatic Ecosystems Exploration: Freshwater vs Saltwater Habitats

The video explains the differences between freshwater and saltwater ecosystems, highlighting the unique habitats and organisms in each. Freshwater ecosystems, like ponds and swamps, have minimal salt, while saltwater ecosystems, such as oceans, are very salty and have distinct zones. The video also discusses the types of organisms found in these ecosystems, including fish, plants, and other aquatic life.
