C
A - Feeding is not the only part of symbiosis as well as the latter is not about only feeding.
D - there are at least two roles described: Prey and Predator;
B - would be good title for the third paragraph
E - too general and broad

the appropriate title for this passage seems to be the answer choice D as the paragraph discusses the role played by molluscs

I got D. I took about 3 mins and 45 secs for this one, what would be the ideal time for solving this qsn?DanaJ wrote: So the answer is indeed D here.
A is incorrect because filterfeeding in bivalves is only discussed in the second (relatively short) paragraph, which makes this unsuited as a title of a huge, detailed passage like this one.
B is also incorrect because plankton is only mentioned once, in the very end of paragraph 1: ..and the floating larval stages form a very important part of the zooplankton that sustains life in the waters...
C is wrong because there's really not much talk about prey and predator or the tropical seas themselves. The molluscs don't really "prey" on anything, they sit in a place and filter water! Plus, "tropical seas" are only mentioned in the very end of the third paragraph.
D is correct because it encapsulates much of what's said in paragraph 1 (molluscs are both constructive and destructive forces in the reef), paragraph 2 (molluscs filter water and minute organisms) and 3 (molluscs farm certain small creatures).
E is wrong because there's no mentioning of Coelenterates. If you can believe it, I learned about Coelenterates in 6th grade - my biology teacher was kindda crazy and had us learn scientific terms for animals and plants! Euglena Viridis, Paramoecium Caudatum... Still remember these!

D is the pretty obvious answer i guess. The passage was so long and boring, but the answer was surprisingly easy to eliminate.
IMO (D) .
A) Too narrow. This only covered in paragraph 2.
B) don't recall any large focus on plankton. One word wrong = all wrong
C) Tropical seas wrong, plankton located in reefs.
D) Strong Answer: Molluscs introduced first, spoken more about in second, and third method of feeding.
E) couldnt find Coelenterates anywhere

Consider the opening and closing lines of the piece; they use the words "role," "linked," and "ecosystem." Not that the question ends right there, but it certainly points us towards D.olegpoi wrote:C
