| Emergent macrophytes are a major source of organic matter production in freshwater wetlands, and often represent the bulk of the plant material entering the detrital pool. |
| Dense growths of aquatic macrophytes are generally objectionable to the swimmer, diver, water-skier, and scuba enthusiast. |
| Sessile aquatic macrophytes, however, cannot maintain the same well-defined three-dimensional structure because of the strong drag and shear forces of moving water. |
| Major groups of the inland aquatic biota that are derived from terrestrial ancestors are insects and macrophytes other than large algae. |
| The shade effect of these layers can reduce the productivity of macrophytes below the canopy. |
| Most plant dry mass in the diet of Barrow's Goldeneyes consisted of seeds of submergent and emergent macrophytes, particularly those of pondweeds, mare's tails, and bulrushes. |
