APA style is also widely used for college and university papers. 1  As well as MLA, APA papers are also double-spaced with 1-inch margins on each side. 2  APA guidelines recommend you to use readable and clear font, such as Times New Roman, 12 pt.  The main distinction of APA style is a ârunning headâ at the top of each page.
Interestingly, the largest shark species, the whale shark, does not hunt at all. Enormous whale sharks, megamouth sharks and basking sharks filter feed on plankton. These species have specialized gills that sift through water to extract the microscopic algae and sea creatures that comprise plankton.
Scallops filter plankton from the water internally. Squid eat small fish which eat plankton, and even the mighty humpback whale dines on small fish which eat plankton. Higher on the food chain, sharks eat fish, which eat smaller fish, which eat plankton. Without zooplankton, small fish would starve, and without them, the larger fish would starve. So, nearly everything in the ocean somehow depends on the zooplankton. But the zooplankton eat the phytoplankton, so ultimately, the drifting phytoplankton keep the entire ecosystem in the ocean going.
