There are many things I learned about plankton this week. I learned that they come in two types, zooplankton and phytoplankton. I learned that they are the base of the oceanic food chain. I learned that they can produce an underwater snow effect when they die and fall to the bottom of the ocean. I learned that plankton can cause problems if they are too numerous and I learned that animals can grow out of being plankton as they mature.
