Planktons consists of tiny living sea creatures and plants which they emerged from their larve or egg stages and the living plant algae. They are also marine thrifts and are passively floating or weakly swimming usually minute animal and plant life in the ocean. In addition, there are two terms of planktons, zooplanktons and phytoplanktons. Zooplanktons are very tiny sea creatures and can be larger size as krill, (shrimplike creatures) swims in the water along with phytoplanktons which is thousands of species of tiny plants and algae that floats in the ocean. Zooplanktons eats phytoplanktons. The larger sea creatures such as fish or whales eats zooplanktons and other names called the "krills" ( thousands of tiny shrimps) and tiny jellyfishes. Many larger animals eat just phytoplankton as well. Whale sharks eat nothing but phytoplankton.
Plankton is a mix of plants and animals, the plants "eat" sunlight, the animals eat the plants and each other.
