Phytoplankton + Productivity 5E This lesson ties ocean/float data to the concept of primary productivity by looking for connections between chlorophyll-a and dissolved oxygen.Primary productivity is the rate at which solar energy is converted through photosynthesis, aka plant/algae/organism growth. More productive ecosystems support more life and are more biodiverse, helping those ecosystems rebound from environmental change. This lesson would be used to tie ocean/float data to the concept of productivity by looking for connections between chlorophyll-a and dissolved oxygen.

Half the primary productivity on Earth takes place in the sunlit layers of the ocean and the ocean absorbs roughly half of all carbon dioxide added to the atmosphere.
