Lotic

Wetland
Correct Answer:
B. Lotic
Explanation:
The term lotic refers to freshwater ecosystems characterized by actively moving or flowing water, such as rivers, streams, and springs. This classification is derived from the Latin word lotus, meaning washed, highlighting the unidirectional current that defines these environments. In contrast, lentic ecosystems consist of still or standing water, such as lakes and ponds, while marine ecosystems are defined by high salinity, and wetlands are areas where the soil is saturated or inundated. Therefore, lotic is the specific term used to describe the dynamic, flowing nature of riverine systems.
