Living in flowing water can be beneficial to plants and algae because the current is usually well aerated and it provides a continuous supply of nutrients.These organisms are limited by flow, light, water chemistry, substrate, and grazing pressure.Algae and plants are important to lotic systems as sources of energy, for forming microhabitats that shelter other fauna from predators and the current, and as a food resource (Brown 1987).
