Water Quality B/C

Correct. Your turn!

1. Under what broad category does larvae of the Nassau grouper fall (nekton, plankton, benthos)?
2. In what scenario could supersaturation of aragonite be achieved?
3. Define meromictic.

[SilverBreeze]

1. plankton
2. higher temperatures(near equator/tropics)
3. only the top of the lake mixes... I thought this was a freshwater topic?

Oops, forgot to take out freshwater terms from my vocab section. All looks good, though, except meromictic is more no mixing whatsoever. Your turn.

[SilverBreeze]

1. What is the most common ion in seawater?
2. Name three types of symbiosis and describe them.
3. High river input and low tidal forces result in what type of estuary?

1. Chloride (Cl-)
2. Mutualism (both benefit), commensalism (one benefits, one unaffected), parasitism (one is harmed but not killed, other benefits)
3. Well-mixed

I believe the last one may be salt wedge, but otherwise all correct. Your turn!

[jimmy-bond]

1. What organism utilizes calcification for self-defense?
2. How does a water softener work?
3. Define teleplanic as an adjective describing larvae.

[SilverBreeze]

1. coral, molluscs, crustaceans, etc.
2. Ca and Mg ions(what make the water hard) are removed, such as by replacing them with sodium(resin beads) or using lime(causing precipitation)
3. The organism stays in a planktonic larval stage for a long time, allowing it to disperse widely.

Guess I was too vague for the first question. All are correct, so your turn
