The largest estuary in the United Staes is the Chesapeake Bay, which extends through six
states, including Maryland, Virginia, and Pennsylvania. The bay is one of the most productive
natural areas in the world. It is home to thousands of plants and animals, including many
commercially important species. The water of the bay is relatively shallow. Many areas are no
more than 10 feet deep, with an average depth of 30 feet. Light penetrates the shallow water
and supports the submerged plants that provide food and shelter for the many species living
in the bay ecosystem. However, like many estuaries, the bay receives large amounts of
fertilizer runoff form farms, lawns, and wastewater treatment facilities. Fertilizer runoff
contains______, which are the most important limiting factors for phytoplankton growth.
A) carbon and hydrogen
B) oxygen and carbon dioxide
C) nitrogen and phosphorus
D) sulfur and magnesium
C) nitrogen and phosphorus
The primary source of energy for hydrothermal vent communities is
A) the heat of the water emerging from the vents
B) oxidation of petroleum compounds in the vent water
C) oxidation of hydrogen sulfide in the vent water
D) reduction of carbon dioxide in the vent water
C) oxidation of hydrogen sulfide in the vent water
The immediate results of the widespread use of pesticides and fertilizers included____, but
long term results included_____.
A) dramatic increases in crow yields...the evolution of pest resistance
B) global declines in undesirable pests, such as mice, rats, crows, and sharks...increases in
these pests
C) the increased spread of malaria....delayed resistance to pesticides
D) terrible declines in agricultural productivity....world wide distraction of DDT
