Round 8: Tossup 18

These organisms appear to violate the competitive exclusion principle in their namesake “paradox” due to having high biodiversity despite existing in the same habitat. Some biologists humorously consider the largest bony fish in the world, the ocean sunfish, to be the largest species of these organisms. (-5[1])Possibly climate-influencing sulfate aerosols are released by photosynthetic types (15[1])of these organisms such (-5[1])as (*) diatoms (-5[2])(“DIE-uh-tomz”). These organisms (10[1])are contrasted with nekton, (10[1])which (-5[1])unlike them are able to swim against the current. (10[1])There are “phyto-” (“FYE-toh”) and “zoo-” (10[2])(”ZOH-oh”) (10[1])varieties of, for 10 points, (10[2])what very small marine organisms? (10[4])■END■ (10[2])
