Plankton. They are the food source of many other marine animals, including those others listed. Without them, the rest of the food chain would perish.

That would probably be the plankton. So many of the other sea creatures rely on the plankton for food, that if you removed them, the fish that eat plankton would also disappear. The fish that ate those fish would in turn disappear etc. The lower down the food chain that you remove an organism, the worse the consequences for all those organisms higher up the food chain.

Plankton because the shrimp feed off of them and so forth. If you took out the whales only the whales would be gone unlike if you took out the plankton everything else would die too.

d. plankton.
The whales rely on plankton, as do many animals. It is at the bottom of the food chain, and if they were to be eliminated, then that would affect the entire food chain above it.

plankton - it's so low on the food chain that removing it would mean thousands of problems would arise and species would either die off or have to find a way to adapt quickly.

Plankton. They may be small but they are very important.
