  1. Plankton By Dustin Chalton

  2. Phytoplankton is a kind of plant. They’re too small to be individually seen with the unaided eye. However, when present in high numbers, they appear as a green discoloration of the water due to the presence of chlorophyll(a green pigment found in cyanobacteria and the chloroplasts of algae and plants)within their cells (although the actual color may vary with the specie of phytoplankton present due to varying level of chlorophyll or the presence of accessory pigments such as phycobilliproteins, xanthophyll.)

  3. Next, zooplankton is the second kind of plankton. Zooplankton is a animal and they are heterotrophic (sometimes detritivorous)plankton. Plankton are organisms drifting in oceans, seas, and bodies of fresh water. The word zooplankton is derived from the Greek zoon, meaning animal, and planktos, meaning wanderer or drifter. Individual zooplankton is are usually microscopic, but some(such as jellyfish) are larger and visible with the eye. Some zooplankton are larval or many immature stages of larger animals, including mollusks(like snails and squid), crustaceans (like crabs and lobsters), fish, jellyfish, sea –cucumbers, and sea stars(these are called meroplankton.) Some zooplankton are single-celled animals, like foraminifera and radiolarians. Other zooplankton are tiny crustaceans, like Daphnia.(If you krill and copepods, which can swim, this group constitutes about 70 percent of all plankton.

  4. Last of all, there are many facts about plankton.

  5. Plankton are so small that no one knows their exact size.

  6. Plankton are the first link in the marine food chain so it is ate by many organisms, including mussels, fish, birds, and mammals (for example baleen whales.)
