In the study of inland water ecosystems, habitats are broadly categorized based on the movement of water into either lotic (running-water) or lentic (standing-water) systems.1
Lentic ecosystems are defined by their relatively still or standing water. The primary habitats classified as lentic include:
- Lakes: Larger, deeper bodies of water that often exhibit thermal and chemical stratification.21
- Ponds: Relatively shallow bodies of water that typically allow light to penetrate to the bottom, supporting rooted aquatic plants.21
- Marshes: Wetlands characterized by standing water and emergent vegetation.1
Additionally, humans frequently create artificial lentic habitats, such as reservoirs, impoundments, and farm dams. While these categories are distinct, the classification can sometimes be complex; for example, certain areas of large rivers with low flow or extensive floodplains may exhibit characteristics more similar to lentic environments than lotic ones.13
