• Phytoplankton are tiny plants that perform photosynthesis using the sun's energy to grow and reproduce. They are the production link in the food chain.
• Zooplankton are tiny animals that feed mainly on Phytoplankton to grow and reproduce. They are the first consumers link in the food chain.
• Fish and tiny invertebrates, such as sardines and small cephalopods, feed on Zooplankton to grow and reproduce. They are the second consumers link in the food chain. They are predators.
• Fish and large invertebrates, such as tuna and octopus, feed on small fish and invertebrates to grow, reproduce and in turn serve as food for superpredators such as sharks
