Phytoplankton are "plant" Plankton. They can be found in all bodies of water. The majority of them are found in our oceans, but phytoplankton may also be found in lakes, tides pools etc. Phytoplankton are eaten by zooplankton (animal plankton) and other larvae such as fish, crab or lobster larvae, which by the way the larvae is also called plankton, but they would be in the zooplankton category until they grow into juvenile fish, crabs and lobster. Their are also other sea creatures that eat phytoplankton such as sea urchins. Whales that eat plankton such as baleen whales eat zooplankton such as krill.
the relationship is that seens phytoplankton need sunlight to survive and phytoplankton are the base of the food chain they connect to sun to phytoplankton to other sea life
