Re: What would happen if there was no plankton?

Dear TIm (or is it Tim?),
Many species of fish, especially the juveniles, feed on the zooplankton 
(microscopic animals) or on the phytoplankton (algae and bacteria). Many 
of these fish in turn become food for the larger fish, turtles, fish-
eating birds and mammals. As you can see, a lot of animals directly or 
indirectly depend on the plankton for survival. They all form one big 
complex food web. If, for some reason, all the plankton disappeared 
permanently, most, perhaps all, of the animals in this food web would also 
die off.
