plankton facts



This week i learned a lot about plankton that i would have never realized or learned before.
My favorite fact that i learned was that animals like jellyfish and other types of fish can actually begin there life as plankton and then grow into a full sized fish. Another one of my favorites and most surprising was that plankton provide 80% of our oxygen, before learning this i always thought it was from the trees but i was proven wrong. I also learned that plankton can not travel against currents and so they rely on that to get them where they float. There is also plant plankton which have to be near the surface so that they are able to photosynthesize.
