Coccolithophores

A recent study has found that increase in algae known as diatoms has decreased in calcium carbonate concentration in Southern Indian Ocean which will affect the growth of coccolithophores. 

👉These are single-celled algae living in the upper layers of the world's oceans. 

👉They calcify marine phytoplankton that produces up to 40% of open ocean calcium carbonate and responsible for 20% of the global net marine primary productivity. 

👉In the process they help in removing carbon dioxide from atmosphere and ocean.
