Answer:

Marine ecosystem have biotic organisms like phytoplankton and photosynthetic algae that do photosynthesis and converts the atmospheric carbon dioxide into organic matter most of the carbon dioxide is released when other organisms eat phytoplankton and release the carbon dioxide through respiration.

But some of the algae and phytoplanktons die naturally get down to the bottom of the ocean where they make carbon sink. Some organisms accumulate CO₂ in their exoskeleton that is made up of calcium carbonate.

Therefore this use of carbon by living organisms in oceans brings carbon dioxide from the atmosphere to oceans. This is why the ocean plays a critical role in the carbon cycle and called carbon sink.

<h2>Dinoflagellates thrive in bahia fosforescente</h2>

Explanation:

Dinoflagellate, are one-celled aquatic organisms having two dissimilar flagella.
It has a characteristics of both plants and animals.
Most of the dinoflagellates are marine, but some live in freshwater habitats.
Bahia fosforescente is one of the phosphorescent bays where millions of glowing marine dwellers such as dinoflagellates cause the lake to glow a bright blue in night.
Dinoflagellates has the characteristics of Bioluminescence which they use it as a defense mechanism.
During night, due to the bioluminescence of dinoflagellates,water can have an appearance of sparkling light.
Dinoflagellates takes their nutrients from marine organisms, thus they grow or develop well in bahia fosforescente.
