How much CO2 does a pound of phytoplankton take up?

Phytoplankton play a significant role in carbon sequestration, with estimates suggesting that they can absorb about 0.5 to 1.5 grams of CO2 for every gram of biomass produced. Since a pound is approximately 454 grams, this means a pound of phytoplankton could potentially take up around 227 to 681 grams of CO2. The exact amount can vary based on species, environmental conditions, and growth rates. Overall, phytoplankton are crucial in mitigating climate change through their carbon uptake.
