Step 1
Allochthonous inputs refer to organic matter or nutrients that originate from outside the aquatic ecosystem (e.g., from the surrounding terrestrial environment) and are transported into it. In contrast, autochthonous inputs originate from within the aquatic Show more…

Name several major sources of nutrients that enter water ways.
Agricultural ecosystems can export large quantities of nutrients via streams. Farmers often rely on riparian forest strips of forest vegetation immediately adjacent to streams to reduce this flux. William Peterjohn and David Correll, two researchers in Maryland, constructed a nitrogen budget (right) for an agricultural ecosystem that was a mix of corn fields and riparian forest. Q3.24. How much did the corn forest ecosystem retain each year in terms of observed nitrogen fluxes? (Hint: The focus of this study is on the measured anthropogenic inputs displayed in the budget)
