Aquatic vegetables are plants that grow in or near water bodies, such as lakes, rivers, and wetlands. They play a crucial role in aquatic ecosystems by providing habitat and food for various wildlife. Common examples include water lilies, cattails, and duckweed. These plants can thrive in both freshwater and saltwater environments. Many aquatic vegetables are also edible and are used in various cuisines around the world. For instance, lotus root and water spinach are popular in Asian dishes. Additionally, they can be cultivated for their nutritional benefits, as they are often rich in vitamins and minerals.
