Which term describes flowing-water ecosystems such as rivers and streams?

• A. Lentic Systems
• B. Lotic Systems
• C. Pond
• D. Lake

Answer: (B)

Flowing-water ecosystems are described by the term lotic. Rivers and streams continuously move water in one direction, shaping the environment with current, creating habitats like riffles, runs, and pools, and selecting organisms adapted to flow. This distinguishes them from still-water environments, which are called lentic and include ponds and lakes. So lotic best describes the concept of flowing-water ecosystems.
