Blue carbon habitats are important specifically because of their ability to

• remove carbon from the water column and transport it to the atmosphere when they die

• remove carbon from the atmosphere or the water column and transport it to the seafloor when they die

• produce oxygen for the atmosphere

• increase water temperature
