Fish species such as trout depend on cold, well-oxygenated water maintained by upstream hydrological processes. Nutrient inputs can alter food webs by affecting algal growth and aquatic insect populations, which serve as key food sources. These interactions link nutrient cycling to both aquatic and terrestrial ecosystems. |
