Identify Lotic Ecosystem Example

A lotic ecosystem is characterized by flowing water environments.

Key features include unidirectional movement of water.

Evaluating Ecosystem Options

Let's examine the provided options:

• River: Exhibits continuous water flow. This aligns directly with the definition of a lotic ecosystem.
• Grassland: This is a terrestrial ecosystem, not aquatic, and lacks flowing water characteristics.
• Pond: This is a lentic ecosystem, defined by standing or still water.
• Lake: Similar to a pond, a lake is also a lentic ecosystem with still water.

Conclusion

Based on the definition, a river is the only option representing a lotic ecosystem.
