What is the definition of lotic water?

Lotic water refers specifically to flowing water systems, primarily found in rivers and streams. The term "lotic" is derived from the Latin word "loti," meaning to flow. This type of water is characterized by its continuous movement, which influences various ecological dynamics. For example, the flow of lotic water affects the oxygenation levels, temperature, and sediment transport within these ecosystems, creating unique habitats for diverse aquatic organisms.

The definition and characteristics align with option C, identifying these water bodies as faster-moving compared to still water bodies like ponds or lakes. Understanding the dynamics of lotic water is crucial for the study of aquatic ecology, water quality assessment, and management practices, particularly because these systems often have different criteria and metrics for evaluating water quality than stagnant water bodies.
