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.
Answer:
Yes both are different. In directional selection one of the extreme traits is favored, whereas in disruptive selection both the extreme traits are favored.
Explanation:
Directional: If selection acts to eliminate one extreme form and supports the other extreme then the peak shifts in the direction which is selected by the nature.
Disruptive: If the selection does not favor the mean character value, rather favors both the peripheral character values then this kind of selection is called disruptive selection.

Answer:
All the choices are correct
<span>There are two physical differences
between Low pressure systems and </span>High pressure systems.
First, is the circulation surrounding
them.
Secondly, is the atmospheric motion
that they cause.
Low pressure systems circulate counter-clockwise. High pressure systems
circulate clockwise. These "motions" are the
building blocks in our atmosphere. They give us our weather.
A Low’s counter-clockwise circulation forces air upward (ultimately resulting in
condensation, cloud formation and ultimately precipitation). A High’s clockwise
circulation causes a sinking motion in the atmosphere, resulting in fair/clearer
and often sunnier skies.
