Phytoplankton+and+the+Carbon+Cycle

Group 9: Mariah, Joanne Blair emerson parsell Your topic is the role that phytoplankton play in the CO2 balance of the planet. Final Grade- Organization 2 /5 Just one thought? Climate change explanation 1 /10 NEEDS SOME WORK! Oceanography explanation 2 /15 Very little info. Diagram/connection to text 0 /10 None included. Overall 5/40  Phytoplankton are the basis of the food chain. During photosynthesis they obtain water, CO2, and energy to make plant material for other fish to eat. Phytoplankton, if not eaten by other fish, die and sink to the bottom of the ocean and they acquire almost 50% of CO2 out of the atmosphere. In turn they develop about 50% of the oxygen we breathe.
