- A sizable amount of the nitrogen and phosphorus that enters the Chesapeake Bay originates from farms and other faraway sources, yet it is people living near the bay, such as oystermen and crabbers, who bear many of the negative impacts. Who do you believe should be responsible for addressing the problems posed by nutrient pollution? Should policies on this issuebe developed and enforced by state governments, the federal government,both, or neither? Explain the reasons for your answer.arrow_forwardThink for a moment about the carbon, nitrogen, and phosphorus nutrient cycles. You know that human activities have changed each of these nutrient cycles, so that now a percentage of the annual flux is attributable to humans. Rank the nutrient cycles in order of the greatest % human interventior to the least % human intervention. carbon > nitrogen > phosphorus nitrogen > phosphorus > carbon carbon > phosphorus > nitrogen O phosphorus > carbon > nitrogen phosphorus > nitrogen > carbonarrow_forwardPlace the following components of the hydrologic cycle in the correct order by numbering them from 1 to 5, beginning with precipitation. a. precipitation b. uptake by plants c. transpiration d. water percolation into soil e. condensationarrow_forward
