Plankton importance

Plankton are important to our food chain because they are the producers. So if we did not have them, than we would not have any of the bigger fish because they would not have any food. Plankton travel through currents and waves. They need sunlight to survive. An example of a phytoplankton would be a diatom. An example of a zooplankton would be a jellyfish. They are diffent in that the diatom is the producer and the jellyfish is the consumer.
