Why is the water red?
Plankton
microscopic organisms that float.

Two major groups
* phytoplankton–microscopic
plants and bacteria
*zooplankton–microscopic
animals

Phytoplankton
• primary producers (also called autotrophs).
• use chlorophyll to convert energy (from sunlight),
inorganic chemicals (like nitrogen), and dissolved
carbon dioxide gas into carbohydrates.
Zooplankton
Zooplankton
• microscopic animals that eat other plankton.
• Some are larval or very immature stages of
larger animals; mollusks (like snails and
squid), crustaceans (like crabs and lobsters),
fish, jellyfish, sea cucumbers, and seastars
(these are called meroplankton).
• Other zooplankton are single-celled animals,
like foraminifera and radiolarians.
• Other zooplankton are tiny crustaceans, like
daphnia, krill and copepods, this group makes
up about 70 percent of all plankton)
Zooplankton 3 groups
• Microzooplankton–(protozoans and
rotifers) less than 200 microcrons in
size.
• Mesozooplankton–(copepods and
invertebrate larvae) between 200
microns and 2 millimeters in size.
• Macrozooplankton–(amphipods,
shrimp, fish larvae and jelly fish) greater
than 2 millimeters in size.
