Zooplankton and Phytoplankton

There are two different kinds of plankton: zooplankton and phytoplankton. Zooplankton is the animal plankton (you can remember by thinking, animals live in zoos). The phytoplankton is the plant plankton. The animal and plant plankton are at the bottom of the food chain. The animal plankton feeds on plant plankton.
