Round 8: Tossup 18

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