A creek ecosystem is a small, flowing body of water that supports a variety of plants and animals. It typically includes freshwater, which is essential for the survival of many species. The banks of a creek are often lined with vegetation, such as grasses, shrubs, and trees, which provide habitat and food for wildlife. In a creek ecosystem, organisms like fish, insects, and amphibians thrive in the water, while birds and mammals may visit the area for food. The interaction between these species and their environment helps maintain the health of the ecosystem, making it an important part of the larger watershed.
