take them. This includes zooplankton, algae, phytoplankton, and bacteria (G. Karleskint Jr. et al, 2010, p.464). But while it is common to see them as food for fish, they have other roles in nature what make them essential organisms in the delicate balance of our ecosystem. This paper will highlight the critical role of plankton as the organisms that make life on earth possible by describing the foundational role it plays in the food chain and in significant bio-chemical processes and discussing the
