1. Why is the water red?

2. microscopic organisms that float.
Plankton
microscopic organisms that float.
phytoplankton
zooplankton

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

4. Phytoplankton primary producers (also called autotrophs).
use chlorophyll to convert energy (from sunlight), inorganic chemicals (like nitrogen), and dissolved carbon dioxide gas into carbohydrates.

5. Zooplankton

6. 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)

7. 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.

8. Zooplanktons

9. Phyotoplankton
