What is the role of oceans in the carbon cycle ?

The ocean plays an important part in the carbon cycle. Overall, the ocean is called a carbon 'sink' because it takes up more carbon from the atmosphere than it gives up. ... Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter.

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.
