Porites lobata because it is found worldwide, can be shipped and survive, is vigorous to survive an environmental issue,  and is representative of scleractinians.

None, no species of coral would be representative. I read this somewhere on CORIS

Here is an easy one: Describe the three main steps of sewage treatment (primary, secondary, and tertiary), and be sure to include how BOD relates to the secondary step.

Primary is filtration, Secondary is flocculation, and tertiary is coagulation. BOD is removed from the water during flocculation.

Sorry, that is incorrect. Anyone else care to try?

[hide]I'm not sure...Primary treatment is the physical removal of the treatment. It consists of coagulation,flocculation, and sedimentation. Coagulation adds chemicals such as lime and alum, which makes the particles in the water clump together. Flocculation is the water circulation that helps the particles in the water clump together even more, which results in big flocs. Sedimentation is the phase where the water "settles" in tanks called "primary clarifiers or primary settling tanks." The heavy clumps of floc would sink to the bottom and would be scraped off. Secondary treatment is the biological removal of the treatment. Bacteria or microbes would be added to the wastewater to break down the matter in it. In the tanks, they would constantly increase the amount of oxygen to increase the BOD of these bacteria. BOD is the biochemical oxygen demand. Some of the matter would be removed and reused to encourage decomposition in wastewater later on... The teritary treatment is the chemical removal of the treatment. They would add certain chemicals to moderate the levels of phosphate and nitrates before sending the water for storage or releasing it back to the environment.[/hide]

Good job! Very detailed answer. Your turn.
