When quantities of these elements are released into aquatic ecosystems, algal blooms often form in response.

	'''What are Algal Blooms?'''		'''What are Algal Blooms?'''

-	Algal blooms are the “rapid excessive growth of algae, generally caused by high nutrient levels and favorable conditions. [They can] result in deoxygenation of the water mass when the algae die, leading to the death of aquatic flora and fauna” often known as creating hypoxic zones. Algal blooms can occur in both saltwater and freshwater environments although they may be more prevalent in salt water ecosystems. Because of the variety species of algae that live in these two distinct environments, algal blooms vary in color ranging from green to a yellow-brown to a red (which is more commonly known as a red tide).	+	Algal blooms are the “rapid excessive growth of algae, generally caused by high nutrient levels and favorable conditions.

		+	'''How are Algal Blooms created?'''
		+
		+	Algal blooms occur in response to an increase in the quantity of a limiting nutrient in the aquatic ecosystem, most often nitrogen or phosphorus. When these chemicals come in contact with the body of water the algae and phytoplankton take advantage of the abundance of these nutrients and grow and multiply sometimes reaching concentrations of hundreds of thousands per millimeter. <ref>“Algal Bloom”. Science Daily. 1995-2009. <http://www.sciencedaily.com/articles/a/algal_bloom.htm></ref>

	'''How do Algal Blooms affect the Ecosystems of the Chesapeake Bay?'''		'''How do Algal Blooms affect the Ecosystems of the Chesapeake Bay?'''

-	For the Chesapeake Bay, many of the sources of nutrient pollution come from: farm fertilizer runoff (both manure and chemical fertilizer), farm pesticide runoff, and air pollution. “Air pollution from vehicles, industries, gas-powered lawn tools and other emitting sources contribute nearly one-third of the total nitrogen load to the Chesapeake's waterways.” In 2008 alone the Chesapeake Bay absorbed 13.8 million pounds of phosphorus and 291 million pounds of nitrogen. 38% of the total nitrogen content in the Chesapeake Bay comes from agricultural practices while 45% of the total phosphorus content in the Chesapeake Bay comes from agricultural origins. Algal blooms triggered by these pollutants create problems in the Chesapeake Bay in that they block the sunlight from reaching underwater grasses which provide food for birds and shelter for fish and crabs. Algal blooms also absorb the oxygen in the water, thus creating hypoxic zones where no species can effectively live and degrading the biodiversity of the ecosystem. <ref>~~{{cite web \| title =Nutrients \| work =Chesapeke~~ Bay Program:A Watershed Partnership~~\| url =~~http://www.chesapeakebay.net/nutrients.aspx?menuitem=14690~~\| accessdate = 2009-15-09 }}~~</ref>	+	For the Chesapeake Bay, many of the sources of nutrient pollution come from: farm fertilizer runoff (both manure and chemical fertilizer), farm pesticide runoff, and air pollution. “Air pollution from vehicles, industries, gas-powered lawn tools and other emitting sources contribute nearly one-third of the total nitrogen load to the Chesapeake's waterways.” <ref>“Nutrients”.
