The Role of Phytoplanktons in the Environment and in Human Life, a Review

Abstract

Phytoplankton is microscopic organisms that lie in watery environment and make their own food from sunlight through photosynthesis. Phytoplanktons are the core producers and major role play to the food web. They produce the similar amount of biomass of CO₂ as all terrestrial plants combined. Several environmental factors, many of which are currently undergoing significant changes as a result of human-caused global warming, control phytoplankton productivity. Generally, ocean ecosystem is based on phytoplankton. It contributes about half of the world’s primary production, and diverse phytoplankton taxa play distinctive roles in the earth biogeochemical cycles, biological pump, ocean food chain, bioindicator, food industry and drugs. In the present paper an effort has been made to give broad review of literature on phytoplankton. This review clearly indicates that such research is necessary and emphasis the urgency of present work. The recent review highlights the value of phytoplankton in our lives and environment.
