Answer ONE of the following questions in a 300-500 word response. Cite reference materials using proper MLA or APA bibliographic citation.

Here are this week's essay questions:

1) Name the eight (8) major groups of zooplankton and describe the characteristics of each group.

NOTE: This one gets a bit confusing so here's some help: Plankton are classified in 2 ways, by physical size(pico, micro, mero) and by biological group. So answer this by citing the biological groups with biological group. A hint chordate means spinal cord (thus vertebrate) fish larva mostly.
