The lotic zone is the region in a body of water where the water is in a continuous state of motion, meaning it is dynamic. It encompasses flowing freshwater ecosystems.
In simpler terms, the lotic zone refers to any flowing body of water, such as rivers, streams, and creeks. The characteristics of the lotic zone are significantly influenced by the flow of water, including factors such as water velocity, turbulence, and substrate composition. This flowing water distinguishes it from lentic ecosystems, which are characterized by standing water, like lakes and ponds. The constant movement of water affects the oxygen levels, temperature, and nutrient availability, which in turn influence the types of organisms that can survive and thrive in these environments.
