Phytoplankton

• Phytoplankton are microscopic plants that live in the ocean.These small plants are very important to the ocean and to the whole planet.
• They are at the base of the food chain. Many small fish and whales eat them. Then bigger fish eat the little fish, etc.
• The food chain continues and at some point in time we (people) come into it when we eat the fish. So the energy of plankton becomes our energy too.
