Chesapeake bay is an area that has suffered from overharvesting and eutrophication. Eutrophication is an enrichment of water by nutrients salts that causes structural changes in the ecosystem such as increased formation of algae and aquatic plants, depletion of fish species among other effects. The greatest source of nitrogen and phosphorus in a Chesapeake bay is agriculture

Answer:
The organisms in the marine ecosystem converts carbon dioxide to oxygen faster than organisms in other ecosystems.
Explanation:
Simply the organism in the ecosystem seaweed and phytoplanktons makes use of CO2, water, and sunlight to synthesize foods for energy production.During this processes, O2 is liberated as by products from the photolysis of water. These marine photsynthesizers ensures abundant supply of oxygen to the atmosphere.
