New questions!

1. Which organism on the species list attracts fish to "clean" parasites from by having striking coloration and performing "dances"?
2. Which organism on the species list belongs to the phylum Cnidaria, but is not considered a reef-building organism?
3. High-trophic-level predators such as groupers often contain high concentrations of toxins such as methylmercury. What is this phenomenon called, and why does it occur?

1. Banded coral shrimp
2. Gorgonia
3. Biomagnification- organisms low on the food chain may each have a small amount of the toxins; larger organisms eat a lot of the smaller organisms and end up with a lot of the toxin. This continues up the food chain until the top predators have high concentrations of the toxin.

1. Explain the difference between top-down and bottom-up trophic cascades.
2. Explain some of the uses of phosphorus in organisms.
3. Let's say there's a fish which is toxic and has warning coloration. Another non-toxic fish evolves to have similar coloration. What type of mimicry is this, and who benefits (toxic fish, non-toxic fish, predator)?

1. top-down is when predators control populations by how many prey they eat, and how many prey those remaining prey eat, etc., while bottom-up is when producers control populations by how much energy they fix from the sun into the system, and how much the primary consumers allow the secondary consumers to access it, etc.
2. DNA backbone, bone structure, ATP, phospholipids in cell membrane
3. Batesian mimicry; non-toxic benefits

1. True or false: fan corals have zooxanthellae.
2. What is the second-most common positive ion in the ocean?
3. Describe the shell of a dead flamingo tongue snail.

1 true, for at least some 2 Magnesium, as Mg2+ 3 Blank and off-white, like bone (is it bone?), with a ridge around the middle (additional question, how do you get the answers on separate lines, the ENTER key isn't working right for this for me)

Correct, although it's not bone.
For getting a new line between spoiler and hide tags, you need to hit enter four times.
So

Code: Select all

[spoiler]hi[/spoiler]
[spoiler]hello[/spoiler]
displays as: hi hello


While

Code: Select all

[spoiler]hi[/spoiler]



[spoiler]hello[/spoiler]
displays as

hi
hello

Thank you, Ms. Breeze.

1. How much energy is lost between trophic levels, and what is this called?
2. Please provide a brief description of mutualism, commensalism, and parasitism.
3. Please explain the difference between a niche and a habitat.
